Answer:

D

Explanation:

The formula for the area of a circle is pi times radius squared.

The radius is half of the diameter, so 24/2 = 12

12^2 x pi

Answer:

$12^2 \pi$

Explanation:

Since, the area of a circle,

$A=\pi r^2$

Where,

r = radius of the circle,

Given,

Diameter of the circle = 24 inches,

So, the radius of the circle, r =
(Diameter)/(2) =
(24)/(2) = 12 inches,

Thus, the area of the circle is,

$A=12^2 \pi \text{ square inches}$

OPTION D is correct.
