The area of a circle is given by the following equation:


A\text{ = }\pi r^2

In which r is the radius.

In this question, we have a radius of 42 inches.

Using pi = 3.14, the area is:


A\text{ = 3.14}\cdot(42)^2\text{ = }5539

Since the radius in inches, the area is measured in squared inches.

The area is 5539 squared inches.
