Finding the radius when given the circumference

The video tutorial explains how to find the radius of a circle when given the circumference. It begins by introducing the relationship between circumference, diameter, and radius, using the formula C = πD or C = 2πr. The tutorial then demonstrates how to solve for the diameter when the circumference is known, using a given example where the circumference is 24π. Finally, it shows how to calculate the radius from the diameter and verifies the solution, ensuring the understanding of the mathematical process involved.
