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?
Diameter of the cylindrical bowl cm
Radius of the cylindrical bowl cm
Height of soup in the cylindrical bowl cm
Volume of soup in the cylindrical bowl = Soup given to 1 patient
Volume of soup needed for 250 patients
Therefore, soup needed for 250 patients = 38.5 litres
