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?


Radius ( r ) of cylindrical bowl = = 3.5 cm


Height (h) of bowl, up to which bowl is filled with soup = 4 cm


Volume of soup in 1 bowl = πr2h


= * 3.5 * 3.5 * 4


= (11 × 3.5 × 4)


= 154 cm3


Volume of soup given to 250 patients = (250 × 154) cm3


= 38500 cm3


= 38.5 litres
