In the diagram above, a cylinder is summounted by a hemisphere bowl. Calculate the volume of the solid.

Correct Answer: Option D

Explanation

Volume of cylinder = πr²h
= π x 3² x 20
= π x 9 x 20
= 180 πcm³
Volume of hemisphere = ²/_3πr³
= ²/₃ x π x 3²
= 2 x π x 3²
= 2 x π x 9
= 18π
= Volume of the solid = 180π x 18π
= 198πcm³
