Step-by-step explanation:
Let the radius be = r
we know that the length of the sheet =
circumference of the circle
Height of the cylinder = 18 cm
44 2r
2x 22/7r= 44
r (44 x 7) / (22 x 2)
r 7 cm
Volume of cylinder = r^2 .h
22/7 7*7 18
= 2772cm³

height of cylinder = 42 cm
diameter of cylinder = 50 cm
then radius = 25 cm
volume of cylinder
= 22/7 x 25 x 25 x 42
= 82,500 cm³
