If a hemisphere is melted and four spheres of equal volume are made, the radius of each sphere will be equal to
-
-
1 th of the radius of the hemisphere 4
- radius of the hemisphere
-
1 of the radius of the hemisphere 2 -
1 th of the radius of the hemisphere 6
-
Correct Option: C
Volume of hemisphere = | πR³ cu. units | |
3 |
Volume of newphere = | πr³ cu. units | |
3 |
According to the question,
πR³ = 4 × | πr³ | |||
3 | 3 |
⇒ R³ = 8r³
⇒ R = 2r units
∴ r = | R Units | |
