A patient in a hospital is given soup daily in a cylindrical bowl of diameter 7 cm. If the bowl is filled with soup to a height of 4 cm, how much soup the hospital has to prepare daily to serve 250 patients?
Given,
Diameter of cylindrical bowl = 7 cm
So radius of bowl = 
Height of soup in bowl = 4 cm
Volume of soup in 1 bowl = πr2h =
For 250 patients volume of soup prepared = 250 ×154 = 38500 cm3
=
