Two cones have their heights in the ratio 1 : 3 and the radii of their bases are in the ratio 3 : 1. The ratio of their volume is
Correct Answer: Description for Correct answer:
Let height of the cones are h and 3h and radii of their base are 3r and r respectively.
So ratio of their volumes = \( \large \frac{\frac{1}{3} \pi \left(3r\right)^2 h } {\frac{1}{3} \pi r^2 (3h)} = 3\) i.e., 3 : 1
