You can if you want to. The answer will always be (2 pi) x (radius)2 .
I don't know how that would be helpful.

The circumference of a circle if the radius is 18 is: 113i have the same question and its multiple choice and none of the choices say 113! :((
Circumference = 2*pi*radius Radius = Circumference/(2*pi)
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius.

It does not matter if the radius is an integer or a fraction.
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
