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.

What is the radius used in the calculation of the arc length in the problem?

What is the formula for calculating the length of an arc based on the central angle and radius?

How do you determine the measure of the central angle KLM in the given problem?

Calculate the length from K to M through L using the provided formula and values.

Explain the significance of the units used in the final answer for the length of the arc.
