A Correct answer
Explanation

Curved surface area = 2 * pi * r * h = 528. Circumference = 2 * pi * r = 44. Substituting: 44 * h = 528. h = 528 / 44 = 12 cm.

AI explanation

Using the formula for the curved surface area of a cylinder, 2*pi*r*h equals 528. We are given the base circumference, so 2*pi*r equals 44. Dividing 528 by 44 gives the height, which is 12 cm.
