Learn to determine the length of an arc for a circle

The video tutorial explains how to calculate the length of an arc in a circle. It begins by discussing central angles and arcs, then sets up a problem to find the arc length between points K, L, and M. The teacher identifies the radius and introduces the formula for arc length: (angle/360) * 2πR. The calculation is demonstrated, resulting in an arc length of 25.43 millimeters. The tutorial concludes by clarifying the units used for distance.
