Here we will explain, calculate, and show you what fraction of a circle 21 degrees is. More specifically, if you draw two lines from the center of a circle, creating 21 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 21 over 360 and simplify if necessary, we get the answer to "What fraction of a circle is 21 degrees?" as follows:
degrees/360 = fraction
21/360 = 7/120
21 degrees = 7/120
Below is an illustration showing you what 21 degrees and 7/120 of a circle looks like.
To create the illustration above showing you 21 degrees, we first drew a circle and then drew two lines from the center, separated by 21 degrees. The slice that the two lines create inside the circle is 7/120 of the circle.
