Area and Volume of a Prism

The video tutorial explains how to find the radius of a circle when given the area. It starts with a problem involving a sprinkler watering a circular area of 1600 Pi square meters. The tutorial walks through the formula for the area of a circle, A = π * r^2, and demonstrates how to solve for the radius by dividing both sides by π and taking the square root of the result. The instructor uses mental math to find that the radius is 40 meters, concluding with a summary of the method.

Explain the process of solving for the radius in this problem.

What is the value of the radius when the area is 1600 Pi square meters?
