Given the radius of a circle find the length of an arc

The video tutorial covers a homework problem where students are tasked with finding the length of arc LM. The instructor explains the formula for calculating arc length, which involves the central angle, radius, and π. The formula is applied to a specific example where the central angle is 100 degrees and the radius is 5 inches. The instructor demonstrates the calculation process and emphasizes the importance of using the correct units. Finally, guidance is provided for completing similar problems in the homework assignment.
