Find the arc and explain why theta cannot be in degrees

The video tutorial explains how to measure the arc length of a circle using radians. It begins by introducing the concept of radians as a measure of rotation, contrasting it with degrees. The tutorial then provides a formula for calculating arc length, emphasizing the importance of using radians in the formula. It highlights the differences between radians and degrees, demonstrating why radians are preferred for these calculations. The video concludes with a summary of the key points discussed.
