-
The respective height and volume of a hemisphere and a right circular cylinder are equal, then the ratio of their radii is
-
- 2 : 3
- 3 : 1
- 3 : 2
- 2 : 3
- 2 : 3
Correct Option: C
Let Radius of hemisphere = Height of cylinder = r units
| ∴ | = 1 | |
| Volume of cylinder |
| ⇒ | πr³h | = 1 ⇒ | = | ||
| 3 | πr1² | 3 | |||
| r1² | r² | 2 | |||
| ⇒ | = | or √3 : √2 | ||
| r1 | √2 |
