If radi of two cylinders are in the ration 3 : 2 and their height in the ratio 4 : 3, then ratio of their volumes is

A) 9 : 8
B) 2 : 1
C) 3 : 1
D) 4 : 1

Correct Answer:



C) 3 : 1

Description for Correct answer:

Let radii of two cylinders respectively be 3r and 2r and their heights be 4h and 3h.
Ratio of their volumes

= \( \Large \frac{\pi (3r)^2 (4h)}{\pi (2r)^2 3h} \)

=\( \Large \frac{36}{12} \)
= 3 ie.., 3 : 1
