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 of cylindrical bowl r = 7/2 = 3.5 and height of soup inside the cylindrical bowl h = 4 cm
Volume of cylindrical bowl = πr²h
= 22/7 × (3.5)² × 4
= 22/7 × 3.5 × 3.5 × 4
= 22 × 0.5 × 3.5 × 4
= 154 cm³
Therefore, the volume of soup per day for 250 patient = 250 × 154 = 38500 cm³
Hence, hospital has to prepare 38500 cm³ soup daily to serve 250 patients.
