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

Answer:

$V=1398.4\ cm^3$

Step-by-step 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 :

$V=\pi r^2 h\\\\V=\dfrac{22}{7}\times (3.18)^2 \times 44\\\\V=1398.4\ cm^3$

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