If i know the circumference, how do i find the radius and diameter explain in an easy way because i dont understand !

Divide the circumference by pi to get the diameter.

Divide the diameter by 2 to get the radius.

The relationships are usually expressed as

... C = πd . . . . or . . . . C = 2πr

... d = 2r

Using the first equation, divide by the coefficient of d to find d:

... C/π = d

Using the second equation, divide by the coefficient of r to find r:

... d/2 = r
