Question

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?

Answer 1

Radius (r) of cylindrical bowl =

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

Volume of soup in 1 bowl = πr²h

= (11 × 3.5 × 4) cm³

= 154 cm³

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

= 38500 cm³

= 38.5 litres.
