When you curled the rectangular sheet along with,
the with of the paper becomes the base circumference of the cylinder and
the length of the paper becomes the height of the cylinder.
Circumference of the cylinder = 20 cm [width of the paper]
2∗π∗r=20cm
r=3.1847 cm
volumeofthecylinder=π∗r2∗hcm3
=π∗(3.1847 *3.1847)*44
=1401.26
