D Correct answer
Explanation

Radius = 12. Area = pi * r^2 = 3.14 * 144 = 452.16.

AI explanation

Using the formula for the area of a circle, which is A = pi*r^2, the radius r is half of the diameter, so r = 24/2 = 12 inches. Substituting the values gives A = 3.14*(12)^2, which equals 3.14*144. The area of the circle is 452.16 square inches.
