What fraction of a circle is 72 degrees?

Here we will explain, calculate, and show you what fraction of a circle 72 degrees is. More specifically, if you draw two lines from the center of a circle, creating 72 degrees, what will the area between the lines be as a fraction of the whole circle?

A full turn on a circle is 360 degrees. Therefore, to calculate what fraction of a circle any number of degrees is, you can simply put the number of degrees over 360.

When we put 72 over 360 and simplify if necessary, we get the answer to "What fraction of a circle is 72 degrees?" as follows:

degrees/360 = fraction
72/360 = 1/5
72 degrees = 1/5

Below is an illustration showing you what 72 degrees and 1/5 of a circle looks like.

To create the illustration above showing you 72 degrees, we first drew a circle and then drew two lines from the center, separated by 72 degrees. The slice that the two lines create inside the circle is 1/5 of the circle.
