C Correct answer
Explanation

Total surface area of a cylinder = 2 * pi * r * (r + h). Using pi = 22/7, Area = 2 * (22/7) * 7 * (7 + 15) = 44 * 22 = 968.

AI explanation

The total surface area of a cylinder is calculated using the formula 2 * pi * r * (r + h). Substituting the given radius of 7 cm and height of 15 cm, and using pi as 22/7, we get 2 * (22/7) * 7 * (7 + 15). This simplifies to 44 * 22, which equals 968 square centimetres. The total surface area is 968 cm2.
