A hemispherical bowlof internal radius 9 cm, contains a liquid. This liquid is to befilled into small cylindrical bottles of diameter 3 cm and height 4 cm.Then the number of bottles necessary to empty the bowl is
Show answer & explanation
Correct answer: D
Explanation
The correct option is 4.
hemispherical bowl of internal radius 9 cm
r = 9
volume of hemispherical bowl 
× π × r3 = × π × 93 = 486π
small cylindrical bottles of diameter 3 cm and height 4 cm
radius = 
volume of cylindrical bottles = πr2h
= π × ×× 4 = 9π
no of bottles required = 
= 54
