What is the diameter of the Earth? What is the ratio to the equator?

The diameter of the Earth.

After the end of World War II, the U.S. Air Force made another more accurate survey using advanced aerial surveying technology. The result is 12713756 meters. In the early 60s of the 20th century, scientists calculated that the diameter of the pole was 12713884 meters with the help of artificial satellites and electronic computers.

In 1976, the International Union of Astronomers announced a figure for the Earth's equatorial radius, based on which the diameter of the pole should be 12713510 meters. Will this figure be revised again in the future? Let's wait and see!

The diameter between the Earth's north and south poles is 12630824 meters. In 1743, the value of the pole diameter was announced: 12707216 meters.

In 1841, the famous German astronomer Bessel carefully calculated a series of data about the Earth. He declared that the extreme diameter of the Earth should be 12712156 meters.

The radius of the Earth's major axis is about 6378 km x2, and the diameter of the Earth's equator is 12756 km

Mean equatorial radius: ae = meters.

The diameter of the Earth's poles should be 12712156 meters.

The radius of the Earth's major axis is about 6378 km x2, and the diameter of the Earth's equator is 12756 km

Calculation of the circumference of a circle.

1. Circumference = Pi.

Diameter, letter formula: c= d.

2. Circumference = Pi radius 2, letter formula: c=2 r.

The length of the curve that encloses the circle is the circumference of the circle. The length of the circumference of the circle, depending on the diameter (radius) of the circle.

Pi is the ratio of the circumference of a circle to its diameter.

In a plane, a moving point is centered on a certain point and a certain length.

A closed curve formed by a degree of rotation is called a circle. A circle has an infinite number of dots.

The set of points in the same plane whose distance to a fixed point is equal to a fixed length is called a circle. Circles can be represented as sets, the standard equations for circles.

Yes (x - a) y - b) r. where o is the center of the circle and r is the radius.

A circle is a type of geometric shape. By definition, a compass is usually used.

to draw a circle. The diameter and radius length of the circle within the same circle are always the same, and the circle has an infinite number of radii and an infinite number of diameters. A circle is an axisymmetric, center-symmetrical figure.

Axis of symmetry. is the straight line where the diameter is located. At the same time, the circle is a "positive infinite polygon", and "infinity" is just a concept.

When the polygon has more sides, its shape, circumference, and area are closer to a circle. So, there is no real circle in the world, and the circle is really just a conceptual figure.

Length of equatorial radius: 6,km. The equator is the longest circumferential line in the trajectory of points on the Earth's surface that rotate with the Earth. Its radius is and its circumference is kilometers.

The equator is the dividing line between the northern and southern hemispheres, which divides the earth into two hemispheres, north of which is the northern hemisphere and south of which is the southern hemisphere, which is the baseline that divides latitude. The equator has a latitude of 0°, which is the longest latitude on Earth. At the same time, the equator is the place where the acceleration of gravity on Earth is minimal.

The sea through which the equator passes:

Gulf of Guinea, Equatorial Strait, Mentawai Strait, South China Sea, Makassar Strait, Tomini Bay, Maluku Sea, Hammahera Sea.

The equator is a low pressure area, and the northeast and southeast trade winds blowing from both sides of the equator to the equator drive the sea water on the north and south sides of the equator to flow from east to west. The north is called the North Equatorial Warm Current, and the south is called the South Equatorial Warm Current. When the equatorial warm current reaches the west coast of the ocean, it is blocked by land, and a small stream of it turns east to form an equatorial countercurrent.

Most of them are affected by geostrophic deflection forces, and flow along the coast to higher latitudes, and are blown by westerly winds in the middle latitudes to form westerly drifting. When they reach the east coast of the ocean, part of them bends to lower latitudes along the west coast of the continent, becoming a compensating current for the equatorial warm current. The other part bends along the west coast of the continent to high latitudes, forming a polar circulation.

Countries passing through the equator:

Indonesia, Nauru, Kiribati, Ecuador (country named after the equator, equator, in Spanish), Colombia, Brazil, Gabon, Congo (Brazzaville), Congo (DRC), Uganda, Rwanda, Kenya, Somalia, Maldives, Singapore.

Kilometer. The equator (equator), a geographical term, refers to the longest circumference in the trajectory of points on the earth's surface with the rotation of the earth. Its radius is and its circumference is kilometers.

Brief introduction: The equator is the dividing line between the northern and southern hemispheres, as well as the zero degree of latitude on Earth. The equatorial region is tropical twice a year, with hot weather and high temperatures.

The center of the equator coincides with the center of the earth, and it is also the longest coil of latitude on the earth, with a total length of more than 40,000 kilometers.

The equator passes through Gabon, Congo, Zaire, Uganda, Kenya, Somalia, Maldives, Indonesia, Ecuador, Colombia and Brazil, among many other countries. In these countries, people use different signs to indicate the equatorial line. In the Congo, for example, the equatorial line is represented by a number of small pillars arranged in a straight line, called equatorial piles.

Summary. Because it is a circle, you can use the circumference formula of the circle:

The circumference c d, is pi, and d is the diameter, so.

c/d＝π＝

Hope mine is helpful to you.

The Earth's equator is a circle, and what is the ratio of the length of the equator to its diameter?

Hello, glad to answer for you. Because it is the source of selling a round hail Zheng tea, you can use the circumference formula of the circle: circumference c d, is the pi plexus band, d is the diameter, so c d hope mine is helpful to you.

If you are satisfied with my answer, I hope to give me a thumbs up! Thank you ( Thank you.)

How many kilometers is the equatorial radius of the Earth longer than the polar radius is described below:

The radius of the equator is 21 kilometers longer than the radius of the pole, and in classical geometry the radius of a circle or circle is any line segment from its center to its periphery, and in more modern use it is also the length of any of them. The name comes from the Latin radius, which means ray, and is also the spokes of a chariot.

The plural of radius can be radius (Latin plural) or regular English plural radius. The typical abbreviation for radius and the name of the mathematical variable is r. By extension, the diameter d is defined as twice the radius:

Split judgment d=2r. If an object does not have a center, the term may refer to its circumference, the radius of its circumscribed circle, or the circumscribed sphere. In either case, the radius can be greater than half of the diameter, which is usually defined as the maximum distance between any two points in the diagram.

Common values for the various radii of the earth are as follows:

1.Polar Radius: The distance from the center of the Earth to the North or South Pole, about 3,950 miles (kilometers) (the difference between the poles is negligible).

2.Earth's equatorial radius: The distance from the center of the earth to the ecliptic tract, about 3,963 miles (kilometers).

3.The average half-diameter of the Earth is about 3959 miles (km). This number is the average of the distance from the center of the earth to all points on the earth's surface.

It can be found as follows: mean radius = (equatorial radius 2 + polar radius) 3

Earth's radius is sometimes used as a unit of distance, especially in astronomy and geology. It is usually denoted by re.

Pole radius length: 6,356 km.

Radius length of the red nucleus cryptopathic Brycephalous nucleus: 6,378 km.

The Earth's equatorial radius is 22 kilometers longer than the polar radius.
