2 What is the volume of a 5 cm ball and how many cubic meters?

Because centimeters are equal to centimeters, equal to meters, and because of the volume of the ball, the formula is equal to 4 3 times the square of pi multiplied by the radius, so the volume of this ball is equal to 4 3, which is about cubic meters.

Analysis: "Centimeters."

This unit (which used to be commonly used, but is now used less) is "centimeter", that is, 1 cm = 1 cm.

For a sphere, the "centimeter" here generally refers to the diameter, i.e., the diameter d=cm, and the radius r=d2=cm.

According to the volume formula of the sphere.

v=4 r 3 , get.

v=4*cm.

Since 1 cubic meter = 10 cubic centimeters.

So there is. v = cubic meter.

Centimeters = meters.

If the diameter is centimeters, the radius is meters.

Rule. The volume is.

4 3) cubic meters.

If the radius is meters.

Rule. The volume is.

4 3) cubic meters.

According to the inscription column, it is calculated as follows:

Volume = 43 r

Cubic centimetre. of -6 cubic meters.

The volume of the ball is about centimeters

The volume of the ball is 4 with a radius of 3, while the centimeter is 25 cm, so it is calculated: 4 cm

50 cm ball 65,450 cubic centimeters, or cubic meters. Solution: v=4 r3 3=4 (2 2)3 3=4 3 (cubic meters).

The volume of a centimeter sphere is obtained by the formula of the perfect square formula and the formula of the area method, and the volume of the sphere is centimeters, which is calculated by the perfect square formula The volume of the centimeter sphere is centimeters.

Diameter cmSphere volumeYesCubic centimetre.

Solution: If the diameter of the ball is known to be centimeters, the radius of the ball is centimeters.

Then the volume of the ball is equal to (4 3)* cubic centimeters.

That is, the diameter of the centimeter and the volume of the sphere are cubic centimeters.

The formula for calculating the ball

The volume of the ball = 3 4 * * the radius of the ball x the radius of the ball x the radius of the ball.

The surface area of the ball.

4* *Radius of the ball* Radius of the ball.

The nature of the ball

The line between the center of the sphere and the center of the circle of the section is perpendicular to the section.

The distance d from the center of the sphere to the cross-section is related to the radius r of the sphere and the radius r of the cross-section: r = r -d. Qing Tsai.

A circle in which the sphere is cut by the plane of the center of the sphere is called a great circle, and a circle that is cut by a section that does not pass through the center of the sphere is called a small circle.

On a sphere, the length of the shortest line between two points is the length of a bad arc between these two points of the great circle passing through these two points, and we take the arc length.

This is called the spherical distance of two points.

The volume of the ball v=4 r 3=1, so the radius of the missing ball r= 3 4. The surface of the ball is buried in the revertent branches s=4 r =4 (3 4) square decimeters.

Sphere volume formula: v 4 r 3 ; Sphere area s=4 r2, note: r sphere radius, : pi. Yuda Zheng

Approximately equal to cubic meters.

Definition of a sphere: A semicircle rotates around the diameter of the straight line to form a space geometry called a sphere, there is no absolute sphere in the world, absolute spheres only exist in theory, but in a weightless environment (such as space), droplets automatically form absolute spheres.

The standard equation for a spherical surface (the center of the sphere represented is (a,b,c) and the radius is r).

Sphere properties: use a plane to intercept a ball, the cross-section is a circular surface, and the cross-section of the ball has the following properties:

1. The line between the center of the sphere and the center of the cross-section circle is perpendicular to the cross-section.

2. The distance d from the center of the sphere to the cross-section has the following relationship with the radius r of the ball and the radius r of the cross-section: r 2=r 2-d 2

3. The circle that is cut by the plane of the sphere through the center of the sphere is called the great circle, and the circle that is intercepted by the section that does not pass through the center of the sphere is called the small imitation circle. On a sphere, the length of the shortest line between two points is the length of a bad arc between these two points of the great circle passing through these two points, and we call this arc length the spherical distance between the two points.

There is a ready-made formula for calculating the area of a sphere known for diameter:

Area = square of diameter.

According to this formula, meters of diameter of the ball.

The area is: s==
