Question

A rectangular piece of paper 11 cm *4cm is folded without overlapping width s cylinder of height 4 CM. Find the volume of the cylinder ​

Answer 1

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× 22/7×r=11

∴r= 7/4cm

Now h=4cm

Volume of the cylinder (V)=πr²h

=22/7×7/4×7/4×4cm²

=38.5 cm²
