Question

The volumes of 2 cylinders are in the ratio of 1:9 and their heights are same.What is the ratio of their radii

Answer 1

Answer:1:3

Step-by-step explanation:

Let the volume of 1st cylinder be V1 and volume of another cylinder be V2

A/q. V1 / V2 = 1/9 =πr^2h / πR^2h

By solving we get 1/9=r^2/R^2

Cancelling square both side we get

1/3=r/R
