Find the Area of a Circle from the Circumference

The video tutorial explains how to solve a standardized math test question about finding the area of a circle. The problem involves a circular mirror with a given circumference of 30 pi inches. The tutorial guides viewers through identifying the formula for the area of a circle, solving for the radius using the circumference, and calculating the area. The solution involves dividing the circumference by 2 pi to find the radius, which is then squared to find the area in terms of pi.

What value do you get for the radius when you solve the equation using the given circumference?

What is the area of the mirror after squaring the radius?
