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
If there is any confusion please leave a comment below.
