## anonymous 5 years ago how to find the circumference of a circle?

1. anonymous

Circumference = 2 * π * radius = π * diameter.

The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter. Pi is the ratio of the circumference of a circle to the diameter. Thus, for any circle, if you divide the circumference by the diameter, you get a value close to Pi. This relationship is expressed in the following formula: C over d equals Pi ( C / d = pi) where C is circumference and d is diameter. ,,Quantum is right

$C = 2\pi r$
