Given the radius and angle in degrees find the arc length

The video tutorial explains how to calculate the arc length of a circle. It begins by introducing the concept and the formula A = r * θ, where A is the arc length, r is the radius, and θ is the angle in radians. The tutorial emphasizes the importance of converting angles from degrees to radians, using 180 degrees as an example, which equals π radians. The calculation is demonstrated by multiplying the radius (15 inches) by π to find the arc length. The video concludes with a reminder to always use radians in such calculations.
