Answer:

The area of the circle is
$\mathbf{6.25\pi}$

Explanation:

Area of a Circle

A circle of radius r has an area calculated by the following formula:

$A=\pi r^2$

The diameter of a circle is twice the radius, thus the radius is half the value of the diameter.

A given circle has a diameter of 5 inches.

The radius of this circle is r = 5/2 = 2.5 inches.

Thus, the area is calculated below:

$A=\pi 2.5^2 = 6.25\pi$

The area of the circle is
$\mathbf{6.25\pi}$
