C Correct answer
Explanation

The diameter is 56 cm, so the radius r = 28 cm. The area of a circle is pi * r^2. Using pi = 22/7, area = (22/7) * 28 * 28 = 22 * 4 * 28 = 88 * 28 = 2464 cm^2.

AI explanation

The radius is half of the diameter, so r = 56 / 2 = 28 cm. Using the area formula for a circle, Area = pi * r^2, we get (22/7) * 28 * 28. This simplifies to 22 * 4 * 28, which equals 2464 cm2. The area is 2464 cm2.
