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.
