Fine the area of a circle that has a diameter of 12 inches A=3.14r2

Alexus [3.1K]

The area of circle is 113.04 in^2

Further explanation:

The area of circle is calculated by using pi and radius.

We are given

Diameter = d = 12 inches

pi = π = 3.14

$r = \frac{d}{2} = \frac{12}{2} = 6\ inches$

$Area = \pi r^2\\= 3.14 * (6)^2\\= 3.14 * 36\\=113.04\ in^2$

The area of circle is 113.04 in^2
