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 | |||||
