Question

A rectangular sheet of paper 44cm*20cm rolled along its length then find volume of cylinder

Answer 1

length of the rectangular sheet l=44cm
breadth of the rectangular sheet b =20cm
then, the radius r of the cylinder=circumference of the base of cylinder =2pir
44=2x22/7r
44x7/44
r=7
height h of the cylinder =20cm
volume of cylinder =pi^2h
V=22/7x7x7x20
V=22x7x20
V=3080cm^3

Answer 2

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

=

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
