A Correct answer
Explanation

Circumference C = 2 * pi * r = 88. Thus, r = 88 / (2 * pi) = 14 m. Area = pi * r^2 = (22/7) * 14 * 14 = 616 m^2.

AI explanation

Using the circumference formula 2 times pi times radius equals 88, we find the radius is 14 m. Applying the area of a circle formula, pi times radius squared, we get 22/7 times 14 squared. This simplifies to 22 times 28, which gives an area of 616 m^2.
