A Correct answer
Explanation

Surface area of a cylinder = 2 * pi * r * (r + h). Here r = 6, h = 8. Area = 2 * 3.14159 * 6 * (6 + 8) = 12 * 3.14159 * 14 = 527.78, which rounds to 528.

AI explanation

The total surface area of a solid cylinder is found by the formula 2 pi r (r + h), where the radius r is half the diameter, which is 6 cm, and the height h is 8 cm. Substituting these values gives 2 times (22/7) times 6 times 14, which equals 528 square cm, making the statement true.
