Question

A rectangular paper of width 22 cm is rolled along its width and cylinder of
radius 16 cm is formed. Find the volume of the cylinder.

Answer 1

Answer:

A rectangular paper of width 14 c is rolled along its width to form a cylinder.

Height of cylinder = h= 14 cm=

width of rectangular paper.

And

Radius of cylinder = r= 20 cm.

Volume of the cylinder = πr2h

$\frac{22}{7} \times 20 \times 20 \times 14 \\ \\ = 17600 {cm}^{3}$

∴ Volume of the cylinder = 17600cm2

Step-by-step explanation:

Answer 2

Height of cylinder = 22 cm

Radius of cylinder = 16 cm

Volume = πr²h

= 3.14 × 16 × 16 × 22

= 17684.48 cm³

If you take π = 22/7 , then the volume is 17700.5 cm³. So check the question what the value of π have to use.
