D Correct answer
Explanation

The curved surface area of a cylinder is given by the formula 2 * pi * r * h. Using pi = 22/7, r = 7, and h = 14, the calculation is 2 * (22/7) * 7 * 14 = 2 * 22 * 14 = 616 cm^2.

AI explanation

The curved surface area of a cylinder is calculated using the formula 2 * pi * r * h. Substituting the given radius of 7 cm and height of 14 cm gives 2 * (22/7) * 7 * 14. This calculates to 44 * 14 = 616 sq cm.
