The circumfrence is like a perimeter. It is the area around a circle. You can find the circumfrence of a circle by using this formula. Pi x R2 or Pi times the radius squared.

Radius of circle: 8/2 = 4 inches

Circle with a radius of 8 feet equals a circle with a diameter of 16 feet.

If the radius of a circle is 8 feet the circumference is about 50.27 feet.

The perimeter of a circle is called its "circumference". Its length is the diameter multiplied by (pi). 8 pi = 25.133 (rounded)

The distance around any object is called its perimeter. The perimeter of a circle has a specific formula: 2(pi)r where pi is a number that is approximately 3.14 and r represents the circle's radius. In this case we are given the circle's diameter, however remember that the diameter of a circle equals two times its radius. So if: d = 50' and d = 2r Then r = 25' Now plus this radius into or equation to get: 2(3.14)(25) = 157' To get the distance around this circle 8 times, multiply the perimeter by 8: 157' * 8 = 1,256 feet

The radius is 8 inches.
