You measure circumference by multiplying the diameter by pi. If it gives you the radius, multiply the radius by 2 to get the diameter then multiply it by pi.
Here are some helpful formulas:
Area: A=Pi r2
Diameter (If given radius) D= r x 2
Radius (If given diameter) R=d/2
Circumference= d x pi

The circumference of a circle measures the distance around the circle.
There is no such specific unit of measure as a circumference - a circumference is merely the distance around something.

Circumference is a linear measure and has no volume - just as a straight line has no volume.
The circumference is the distance around a circle and it is measured by:- Circumference of a circle = 2*pi*radius or pi*diameter
