A rectangular sheet of paper, 44 cm×20 cm, is rolled along its length of form a cylinder. Find the volume of the cylinder so formed.
Given,
Dimension of rectangular sheet = 44cm×20cm
(sheet is rolled along length so length become perimeter and breadth become its height)
=2πr = 44 = r = 
Height = 20 cm
So, volume of cylinder = πr2h =
