Length of the sheet = circumference of cylinder base
2*pi*r=44cm
2*22/7*r=44
r=(44*7)/(2*22)
r=7cm
therefore
cylinder radius=r=7cm
height of the cylinder=breadth of the rectangle
h=18cm
volume of the cylinder =pi*r^2*h
=22/7*7*7*18
=22*7*18
=2772cm^3
2*pi*r=44cm
2*22/7*r=44
r=(44*7)/(2*22)
r=7cm
therefore
cylinder radius=r=7cm
height of the cylinder=breadth of the rectangle
h=18cm
volume of the cylinder =pi*r^2*h
=22/7*7*7*18
=22*7*18
=2772cm^3
