Question

Given two similar cylinders with a height ratio of 2:3 what is the ratio of their volumes?

Answer 1

8 : 27

Explanation:

Given 2 similar cylinders with height ratio = a : b , then

ratio of volumes = a³ : b³

Here height ratio = 2 : 3

ratio of volumes = 2³ : 3³ = 8 : 27

Answer 2

8 : 27

Explanation:

The ratio of the volumes is the ratio of the scale factor cubed

2^3 : 3^3

8 : 27
