Correct option is B
Given:
Curved Surface Area (CSA) = 96π cm²
Height (h) = 12 cm
Formula Used:
CSA of Cylinder = 2πrh
Solution:
2πrh = 96π
2 × r × 12 = 96
24r = 96
=> r = cm
Therefore, the radius of the cylinder is 4 cm.

A cylindrical rod has an outer curved surface area of 8800 cm². If the length of the rod is 87 cm, then the outer radius (in cm) of the rod, correct to two places of decimal, is:
Take π = 22/7
If the radius of the base of a right circular cylinder is decreased by 27% and its height is increased by 237%, then what is the percentage increase (closest integer) in volume?
