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?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 72
Let there are n bottles required to empty the bowl
According to the question
The volume of a hemispherical bowl = n * The volume of the cylindrical bottles
(2/3)πR3 = n * πr2h
(2/3) * 183 = n * 9 * 6
n = 36 * 2 = 72
