Question
A circular cylinder and a hemisphere have the same
radius (r) and the height of the cylinder is equal to the diameter of the hemisphere. Find the ratio of their volumes.Solution
Volume of the cylinder = πr²h Volume of the hemisphere = 2/3 × πr³ (since the height of the cylinder is 2r, which is the diameter of the hemisphere) Ratio of the volumes = (πr²(2r)) / (2/3 × πr³) = 3/1 = 3:1.
