Question

A rectangular sheet of paper is 44cm long and 20cm wide .It is rolled along its length so that the breadths are in contact with each other. find the volume of the cylinder so formed

Answer 1

Thank you for asking this question. Here is your answer:

We know that the length of the rectangular sheet L = 44 cm

and the breadth of the rectangular sheet B =20 cm

The radius r of the cylinder=circumference of the base of cylinder

= $2\pi r$

44=2x22/7r

44x7/44

r=7

and the height h of the cylinder =20cm

volume of cylinder will be π²h

V=22/7x7x7x20

V=22x7x20

V=3080cm³
