Answer:
Given a Rectangular piece of paper 11cm×4cm is folded without overlapping to make a cylinder of height 4 cm
The length of the paper becomes the circumference of the base of the cylinder and width becomes height.
Let radius of the cylinder=r and height=h
Circumference of the base of cylinder =2πr=11cm
⇒2×722×r=11
∴r=47cm
Now h=4cm
Volume of the cylinder (V)=πr2h
=722×47×47×4cm3
=38.5cm3
