Question

6) Pardeep has a rectangular sheet of paper of size 44cm x 20cm. He rolled it

along its breadth and a cylinder is formed. Find volume of the cylinder.​

Answer 1

`V=1398.4\ cm^3`

Explanation:

Given that,

Pardeep has a rectangular sheet of paper of size 44cm x 20cm. He rolled it along its breadth and a cylinder is formed.

When he rolled it along its breadth, 20 is equal to circumference i.e.

20 = 2πr

r is radius of base of cylinder

r = 3.18 cm

44 cm will be height of the cylinder.

The volume of the cylinder is given by :

`V=\pi r^2 h\\\\V=(22)/(7)* (3.18)^2 * 44\\\\V=1398.4\ cm^3`

So, the volume of the cylinder is
`1398.4\ cm^3`.
