You take the radius of 29 centimeters and double it for the diameter - 58 centimeters.Then you could multiply the diameter of 58 centimeters by pi, which is 3.141 (approximately).This would give you the circumference of 182.178 centimeters.

The circumference would be 11.6(pi) or approximately 36.44

A circle with a diameter of 8 would have the circumference of 2.54. This is the measurement inside the circle.

Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.

There is a constant relationship between the radius of a circle and its circumference. This is expressed in a formula.

The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.

You take the radius of 29 centimeters and double it for the diameter - 58 centimeters.Then you could multiply the diameter of 58 centimeters by pi, which is 3.141 (approximately).This would give you the circumference of 182.178 centimeters.

To find the circumference of a circle the equation would be pi multiplied by diameter, or radius squared. the answer would be 31.415 units squared.

That would be the circumference of the circle.

To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159
