Question

The diameter of a circle is 6
inches. What is its
approximate
area?

Answer 1

~28.2743

Explanation:

- The formula for a circle's area is: Area= pi * radius^2

1.) We know the diameter is 6, and the radius is ALWAYS half of the diameter so the radius=3.

2.) Now we square the radius and multiply it by pi, which ends up as ~28.2743 as the area.

Answer 2

A =28.26 inches^2

Explanation:

The diameter is 6 so the radius is d/2 = 3

The area is given by

A = pi r^2

A = pi (3)^2

A = 9pi

Using 3.14 for pi

A = 9 * 3.14

A =28.26 inches^2
