A Correct answer
Explanation

The curved surface area of a cylinder is calculated using the formula 2 * pi * r * h. Using pi = 22/7, r = 14, and h = 8, the calculation is 2 * (22/7) * 14 * 8 = 2 * 22 * 2 * 8 = 704.

AI explanation

The formula for the curved surface area of a right circular cylinder is 2 * pi * r * h. Substituting the given radius of 14 cm and height of 8 cm, the calculation is 2 * (22/7) * 14 * 8. This simplifies to 44 * 2 * 8, resulting in a curved surface area of 704 sq cm.
