**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?**

**Solution:**

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

1000 litre

1 litres

38500 litres

**Therefore, soup needed for 250 patients = 38.5 litres**
