Question

if the length of radii of two solid right circular cylinder are in the ratio 2 : 3 and their height are in the ratio 5 : 3 then the ratio of their volumes is​

Answer 1

let the radius be 2x , 3x ; let the heights be 5x,3x

volume of cylinder = πr^2h

∴ Ratio = π(4x^2)(5x) : π(9x^2)(3x) = 20 : 27
