Question

the radii of two cylinders are in the ratio of 2:3 and their height arein the ratio of 5:4.find the ratio of their volumes​

Answer 1

Answer:

ratio of radii = 2:3

ratio of heights = 5:4

ratio of volumes = pie 2 square 5/pie 3 square 4

Both the pies get cancelled.

= 4 x 5/9 x 4

= 20/36

= 10/18

= 5/9

Therefore, ratio of there volumes is 5:9
