Q14 of 70 Page 19

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 =
