Find the diameter of a circle if the circumference is 52π inches

First we need to know how we usually calculate the circumference of a circle. Usually, we multiply the diameter with π in order to get the circumference, π, which is like a number we use to calculate many answers related to circles or spheres, it has endless decimals therefore we use the notion π.

Therefore, we can let the diameter be d, just an algebra first, and solve it by writing out the equation.

d x π = 52π

Divide π on both sides.

Even if π has a lot of decimals, but since π : π equals 1 anyways, so we don't have to use a calculator for that.

d = 52

Therefore, the diameter is 52.
