Answer 2

Answer:

If a rectangular paper of length 14 cm and width 10 cm is revolved along its width and a cylinder is formed then the volume of the cylinder is $4400 cm^3$.

Step-by-step explanation:

A cylinder is formed by rolling a rectangle about its width. Hence the width of the paper becomes height and the radius of the cylinder is 20 cm.

Height of the cylinder = h = 14 cm

Radius = r = 10 cm

Volume of the cylinder =$V = \pi r^2h$

$=\frac{22}{7} \times 10 \times 10 \times 14$

$= 22 \times 100 \times 2$

$= 4400 cm^3$

Hence, the volume of the cylinder is $4400 cm^3$.
