Learn how to solve for radius r in the formula for circumference of a circle

The video tutorial explains how to solve for the radius (R) in the circumference equation of a circle, C = 2πR. It begins by introducing the equation and the importance of solving for R in geometry. The tutorial then guides viewers through the process of isolating R by dividing both sides of the equation by 2π, resulting in R = C / 2π. Finally, it demonstrates how to apply this solution by substituting the circumference value to find the radius.
