A Correct answer
Explanation

Diameter = 14 cm, so radius = 7 cm. Area = pi * r^2 = (22/7) * 7 * 7 = 154 cm^2. This corresponds to option C.

AI explanation

The area of a circle is found using the formula Area equals pi times the square of the radius. Since the diameter is 14 cm, the radius is 14 divided by 2, which is 7 cm. Substituting the radius and the given value of pi into the formula gives 22/7 times 7 squared, which equals 22 times 7, resulting in an area of 154 square centimeters, corresponding to option C.
