Answer:

144π in²

Explanation:

The area of circle is:

$\displaystyle{A = \pi r^2}$

Where r is radius. Radius is given to be 12 inches. Therefore, substitute r = 12 in the formula:

$\displaystyle{A = \pi \cdot 12^2}\\\\\displaystyle{A=144\pi}$

Therefore, the area is 144π in²

$A=144\pi(in^(2) )$

Let's refer to the formula of the area of a circle:

$A=\pi r^(2)$ , where r is the radius of the circle.

1. Substitute the value of the radius in the formula.

$A=\pi (12in)^(2)$

2. Simplify.

$A=144\pi$

3. Express the answer.

$A=144\pi(in^(2) )$ .
