If the ratio of radii of two cylinders is 2:3 and their heights are in the ratio 5:3, find the ratio of their volumes.

Topic: Geometry &amp; Mensuration
Subtopic: Cylinder

A10 : 9

B20 : 27

C8 : 27

D15 : 16

Explanation

V1 / V2 = (r1^2 * h1) / (r2^2 * h2) = (2^2 * 5) / (3^2 * 3) = (4 * 5) / (9 * 3) = 20 / 27.
