Converting Degrees to Radians

The video tutorial explains the relationship between degrees and radians, focusing on solving a problem to find the radius of a circle given a central angle and arc length. The instructor demonstrates converting degrees to radians and applying the formula for arc length to calculate the radius. The tutorial concludes with a step-by-step calculation using pi as 22/7, resulting in a radius of 35.7 cm.
