Answer:

12 square inches

Explanation:

First, find the radius by dividing the given diameter by 2:

4 in / 2 = 2 in

Now, plug the radius value into the given formula «
$A=\pi r^2$ »:

$A = \pi (2 \, \mathrm{in})^2$

And substitute 3 for π:

$A = 3 (2 \, \mathrm{in})^2$

$A = 3 * 4 \, \mathrm{in}^2$

$A = 12 \, \mathrm{in}^2$

So, the area of the circle is approximately 12 square inches.
