Q1 of 75 Page 230

The circumference of the base of a cylindrical vessel is 132 cm and its height is 25 cm. How many litres of water can it hold? (1000 cm3 = 1l)

Let the radius of the cylindrical vessel be r

Height (h) of vessel = 25 cm


Circumference of vessel = 132 cm


2r = 132 cm


r = ()


= 21 cm


Volume of cylindrical vessel = πr2h


= * 21 * 21 * 25


= 34650 cm3


= () litres


= 34.65 litres
