Question

Two cylinders have their radii in the tatio 4:5 and their heights in the ratio 5:6.Find the ratio of their volumes

Answer 1

Hi friend
--------------

Ratio of radii of two cylinders = 4 : 5

Ratio of heights of two cylinders = 5 : 6

Let the radii be 4r and 5r respectively and the heights be 5h and 6h respectively.

So,

Ratio of volumes = [ π × (4r)² × 5h] / [ π × (5r)² × 6h]

= 16r² × 5h / 25r² × 6h

= 80/150

= 8/15

= 8 : 15
