If you draw a circle with a radius of 29 centimeters what is it's diameter?
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.
What are the circumference of a circle with a 5.8 radius?
The circumference would be 11.6(pi) or approximately 36.44
What is the circumference of the circle if the diameter needs to be 8 centimeters?
A circle with a diameter of 8 would have the circumference of 2.54. This is the measurement inside the circle.
What is the area of a circle in terms of its circumference?
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.
Why would you use a formula to determine the circumference of a circle?
There is a constant relationship between the radius of a circle and its circumference. This is expressed in a formula.
