If two spheres have their radii in the ratio 2 :3, then ratio of their volumes is

A) 8 : 27
B) 4 : 9
C) 6 : 12
D) 1 : 15

Correct Answer:

A) 8 : 27

Description for Correct answer:

Let the radii of 2 spheres are 2r and 3r

Ratio of their volumes
= \( \Large \frac{\frac{4}{3} \pi (2r)^3}{\frac{4}{3} \pi (3r)^3} \)

= 8/27 = 8 : 27
