What is the formula to determine the length of an arc

The video tutorial explains how to label arcs on a unit circle by their endpoints and measure minor and major arcs. It covers the concept of arc measurement in degrees and how to calculate the length of an arc using the central angle. The tutorial also clarifies the difference between the degree of rotation and the actual distance of an arc.
