The heights of a cone and a cylinder are equal. The radii of their bases are in the ratio 2 : 1. The ratio of their volumes is :
-
- 4 : 3
- 3 : 4
- 2 : 1
- 1 : 2
- 4 : 3
Correct Option: A
Radius of the base of cone = 2r units
Radius of the base of cylinder = r units
Height of cone = height of cylinder = h units
| ∴ Required ratio = | π(2r)² × h | ||
| πr²h | |||
| = | = | : 4 : 3 | |||
| 3 | πr²h | 3 |
