B
Correct answer
Explanation
The curved surface area of a cylinder is given by the circumference of the base multiplied by the height, which is 2 * pi * r * h.
AI explanation
The curved surface area of a cylinder represents the area of its lateral sides, excluding the top and bottom bases. The formula for this lateral surface area is 2 times pi times radius times height. Therefore, the curved surface of the cylinder is 2 times pi times r times h.
