Question

2 sheets of paper with measure 22 CM by 28 CM are taken if it is then rolled into cylinder one having the height 22 cm and the other of height 28 CM the difference in their volume in centimetre cube will be

Answer 1

Given rectangular sheet of paper is rolled along its breadth
length = 28 cm breadth = 22 cm
Hence height of cylinder, h = 28
Circumference of the base of cylinder = 2πr = 22 cm
2 × (22/7) × r = 22
Therefore, r = 7/2 = 3.5 cm
Volume of cylinder = πr2h
= (22/7) × (3.5)2 × 28
= 1078 cu cm
Thus the volume of the cylinder is 1078 cu cm.
