A metallic hemisphere is melted and recast in the shape of a cone with the same base radius (R) as that of the hemisphere. If H is the height of the cone, then :
-
- H = 2R
-
H = 2 R 3
- H = √3R
- B = 3R
- H = 2R
Correct Option: A
When we change shape of a solid figure, volume remains constant
∴ Volume of hemisphere = Volume of cone
| ⇒ | πR³= | πR³H | ||
| 3 | 3 |
∴ 2R = H
