Question

the radii of two cylinder are in the ratio 2:3 and their heights are in the ratio 5:3 ;the ratio of their volumes is

Answer 1

we know volume of cylinder =pi.r^2.h
let first cylinder R1 radius and H1 height and second cylindral R2 radius and H2 height
now
volume of 1st cylinder/volume of 2nd cylinder={(R1)^2.H1}/{(R2)^2.H2}
=(2)^2.5/(3)^2. (3)=20/27

Answer 2

Answer:

It is already in the question that the heights are in the ratio 5:3

SO, the answer is

5:3
