					 A hemispherical bowl of internal radius 15 cm contains a liquid. The liquid is to be filled into cylindrical shaped bottles of diameter 5 cm and height 6 cm. The number of bottles required to empty the bowl is
 
- 
                        -  30 
 
-  40 
 
-   50 
 
- 60
 
-  30 
Correct Option: D
| Volume of hemi-spherical bowl = | πr³ | |
| 3 | 
| = |  | π × 15 × 15 × 15 |  | cu.cm. | |
| 3 | 
Volume of a bottle = πR²h
| = π × | × | × 6 cu.cm. | ||
| 2 | 2 | 
| ∴ Number of bottles = | = 60 | ||||||
| 3 × π × | × | × 6 | |||||
| 3 | 3 | ||||||
