Question
A hemispherical bowl of internal radius 18 cm is full of
liquid. This liquid is to be filled in cylindrical bottles each of radius 3 cm and height 6 cm. How many bottles are required to empty the bowl?Solution
ATQ, Total volume of liquid in hemisphere = ((2/3) × π × 183) = 3888π cm3 Let the number of bottles be 'n' Then according to the question: 3888π = n × π × (3)2 × 6 n = 72 ∴ Total number of bottles = 72
