If you fold a circle with a radius of 5 cm in half, what is the length of the line segment formed by

Normally, the line segment of the crease should also be 10 cm, which is relatively normal, because the crease should be its diameter, so it is relatively normal in this regard.

If the radius is 5 centimeters, then the length of the line segment of his crease is of course 10 centimeters, and the length of this line segment is the length of its diameter. The length of the diameter.

If you fold a circle with a radius of 5 cm in half, what is the length of the line segment formed by the crease?

The circle is folded in half once, and the line segment formed by the crease is"Diameter"

Diameter = radius x2 = 5x2 = 10 cm

This should be easy to understand, of course, people are different. The radius of a circle is 5 cm, and it is still 5 cm after folding, and the crease is naturally the diameter, and the diameter is naturally 10 cm.

If the radius is a circle of five centimeters, if you fold it in half, what is the line segment that forms? Actually, that's its diameter, then it's ten centimeters.

If it is normal, its size should be its diameter, so it should be 10 centimeters, which is relatively normal, and it can achieve good results within a reasonable range.

What is the length of the line segment formed by folding a circle with a radius of five centimeters and folding it in half once? I think it's definitely centimeters.

If you fold a circle with a radius of 5 centimeters in half, the degree of the line segment formed by the crease should be centimeters.

What is the length of a line segment when you fold a circle with a radius of 5 cm in half to form a line segment? I don't think that's going to work, and that's probably what it is now.

I'm actually very simple, we know he's half of it if you do it, I hope it helps.

Hello, if you fold a circular piece of paper with a radius of 12 centimeters in half and then fold it in half, and cut it along the line, it is equivalent to dividing the circle into 4 sectors, then its circumference is 8 more radial lengths than the original one, that is, Duoling is 4 12 = 48 cm earlier. Hope mine can help you

Because folding in half once is a semicircle, folding twice is 1 4 yuan, and amusing Fengshan to bend the yard 3 times is 1 8 yuan, so the area is r 8 = square centimeters, and the circumference is d 8 + d = centimeters.

Glad to answer for you Solution: Sterling silver round pieces of paper folded in half once are half circles, and folded twice is 1 4 circles. So first find the area s= *3 * 3 * 1 4 = 9 4 square centimeters) and then find the circumference, it should be noted that in addition to the circumference of 1 4 original round pieces of paper, there are 2 radii that cannot be ignored, so the perimeter is *6 * 1 4 + 3 * 2 = 3 2 + 6 (cm) Note:

It is recommended that Hongshen keep the unit I hope I can help you, thank you

The round piece of paper is a fan-shaped, 1 4 circle, and its radius is r=6 2=3 cm.

Its circumference = 2r + r 2 = 2 3 + cm and its area = r 4 = square centimeter.

The Earth's surface area is 510,065,600 square kilometers. (Of this amount, the ocean area is 362,033,000 square kilometers, accounting for the total area.) The land area is 210,400,000 square kilometers, accounting for a total area; But only two-thirds of it is out of the water, which is actually 148,021,000 square kilometers, or the total area of the Hunger Socks.

The diameter of the poles is 12,km. (The average radius is estimated at 6,356 km.) ）

The maximum circumference of the circle is the equator, 40,km. In comparison, the circumference of the sub-bend circumference is 40,000 km.

Fold it in half three times, and the length of the curve is 1 8 of the length of the circle

Circumference = cm.

Circumference = 2 * Radius.

Radius = divided by (2*cm.)

Diameter = 2 times radius = 4 cm.

The circumference of the circle.

Diameter cm.

The resulting circumference is centimeters, and the area is square centimeters.

Analysis: The area of a circle is multiplied by 2 to the power of 2 equal to the square centimeter. Dividing by 4 equals square centimeters, circumference is multiplied by diameter 2 times 2 equals, and divided by 4 equals centimeters. Fold it in half twice to make a quarter circle.

Circumference = ( r 2) + 2r = cm.

Area = ( r 2) 4 = square centimeters.

A: The circumference of the obtained centimeters, the area is square centimeters.

It's a quarter of this circle! The area of a circle is multiplied by 2 to the power of 2 equal to square centimeters! Dividing by 4 equals square centimeters, circumference is multiplied by diameter 2 times 2 equals, and divided by 4 equals centimeters.

Folding it in half twice is a quarter circle, and the circumference = ( r 2) + 2r = cm.

Area = ( r 2) 4 = square centimeters.

The circumference is centimeters and the area is centimeters.

Circumference = half a circumference, eleven diameters = 6, ten six

6 area = circle area 2=
