Manual

#### Description:

In this Youtube video from TheDouceHouse, he discusses 2 different ways of measuring arc length, by degrees and by distance such as inches. He also show 3 different example problems, problems you will likely see in class, on how to find arc length using a proportion. The three different example have you find arc length, central angle, and radius of circles.
