What is the circumference of a circle with a radius of 72?

Here we will show you how to calculate the circumference of a circle with a radius of 72.

Radius means the straight line distance from the center of a circle to its edge. In this case it is 72. Furthermore, the circumference is the distance around the circle.

The formula to calculate the circumference if you know the radius is as follows:

Circumference = 2 x Radius x π

π = Pi = 3.14, thus, the math to calculate the circumference of a circle with a radius of 72 is:

2 x 72 x 3.14 = 452.16

And the answer to the circumference of a circle with a radius of 72 is approximately:

≈ 452.16

We shortened Pi to two decimal points which is why the answer is just approximate. Pi goes on indefinitely: 3.14159265359.... The more decimal points you use for Pi, the more accurate your answer will be.
