Question

The diameter of a circle is 16 inches. what is the area?

Answer 1

Explanation:

Area = pi * radius squared

`A=\pi r^(2)`

The radius is half of the diameter.

The diameter is 16, so that means the radius is 8

`A=\pi (8)^(2)`

Square 8

`A=\pi * 64`

A=201.06

The area is 201.06 inches
