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
The circumference is twice the radius. In other words, if you know the radius, multiply it by 2 to get the circumference.
