You multiply the diameter by pi, (Approximately 3.14159), so C=pi D.

Circumfrence=diameter X 3.14 (diameter=2 X radius)
The width, or the length of a circle are its diameter.
find the diameter or radius and for the diameter use this equation: d x pi or d x 3.14 and if you want to find the circumference from the radius use this: r x 2 x pi or r x 2 x 3.14. hope i helped :D
Divide the known circumference by pi to find the diameter of the circle.
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
