A solid is a cylinder of radius 7 cm with a hemisphere of the same radius fixed at each end. The total length of the solid is 104 cm. Find its total surface area in cm². Take π = 22/7.

Question

Accepted Answer

4576. The two hemispheres add 7 cm at each end, so the cylinder is 104 − 14 = 90 cm long. Its curved surface = 2 × (22/7) × 7 × 90 = 3960 cm². The two hemispheres together form a sphere of surface 4 × (22/7) × 49 = 616 cm². Total = 3960 + 616 = 4576 cm².

A solid is a cylinder of radius 7 cm with a hemisphere of the same radius fixed at each end. The total length of the solid is 104 cm. Find its total surface area in $cm^{2}$ . Take π = 22/7.
