Question

A rectangular piece of paper 22 cm x 7 cm is
folded without overlapping to make a cylinder of
height 7 cm. Find the volume of the cylinder​

Answer 1

Answer:

Length of paper =22cm

Breadth of paper=7 cm

Height= 7cm

Volume=

$l \times b \times h$

So,

$22 cm\times 7 cm\times 7cm = 1078 \: {cm}^{3}$

Answer 2

Answer:

2,662cm³

Step-by-step explanation:

we have the length and breadth of the rectangular piece is 22cm and 7cm respectively....

now, it folded through its length to form a cylinder of radius 11cm(22/2cm).

we have to find the volume of this cylinder....

and know that the volume of cylinder is,

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \pi(r) {}^{2} h$

so, by putting these values....

we find,

= 22/7×11²×7

= 22×121

= 2,662cm³ .....answer
