Answer 1

Answer:

hey dear ....

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

hope it's helpful for you/.....
