Question

What is the area of a circle with a radius of 42 inches?(Use 3.14 for PL)

Answer 1

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.
