Question

the ratio of radius of two cylinders is 2:3 and the ratio of their height is 3:4 .there volume will be in the ratio of

Answer 1

r1:r2=2x:3x
h1:h2=3x:4x
volume of first cylinder=π(r1)^2h1
=π4x×3x=π12x^2
volume of second cylinder=π9x×4x=π36x^2
now their volume ratio=π12x^2/π36x^2
1/3
ratio=1:3

hope it helps..
