Question
The height of a cylinder and that of a cone are in the
ratio 6:7 and the radii of their bases in the ratio 2:3. The ratio of their volumes will be?Solution
H1:H2 = 6:7 & R1:R2 = 2:3 So ratio of their volume = π x R1 2 x H1/(1/3 x π x R12 x H2) = 3 (R1/R2) 2 x (H1/H2) = 3(2/3) 2 x (6/7) = 8:7
