Step-by-step explanation:
The length of the paper becomes the circumference of the base of the cylinder and width becomes hight .
Let radius of the cylinder= r and height=h
Circumference of the base of cylinder 2r=11cm
=2x22/7xr=11
r=7/4cm
Now h=4cm
Volume of the cylinder (V) =r2h
22/7x7/4x7/4x4cm cube
