A patient in a hospital is given soup daily in a cylindrical bowl of diameter 7cm. If the bowl is filled with soup to a height of 4cm, how much soup the hospital has to prepare daily to serve 250 patients? (Assume π = 22/7)

Solution:

Diameter of cylindrical bowl = 7 cm

Radius of cylindrical bowl, r = 7/2 cm = 3.5 cm

Bowl is filled with soup to a height of4cm, so h = 4 cm

Volume of soup in one bowl= πr2h

(22/7)×3.52×4 = 154

Volume of soup in one bowl is 154 cm3

Therefore,

Volume of soup given to 250 patients = (250×154) cm3= 38500 cm3

= 38.5litres.
