Question

find the volume of a cylinder which is made by rolling a rectangular sheet of size 44m× 14m alng its length?

Answer 1

the rectangular sheet is rolling along its length
so the length become the circumference of its base

circumference of circle= 44m

2πr = 44m

2×22/7×r = 44

r = 44×7/2×22

r = 7

$volume \: of \: cylinder \: = \pi {r}^{2} h$
$volume \: of \: cylinder \: = \frac{22}{7} \times 7 \times 7 \times 14$
volume of cylinder = 2156m

i hope it help u

Answer 2

Answer:

Step-by-step explanation:

Given,

l=44

b=14

Then, it is rolled to form a cylinder

Therefore

, to find the perimeter,

2×22/7*r=14

7=22/7 *r

Therefore, 49/22=r

Therefore,

=22/7 *49/22*49/22*44

Solve it,

We get,

=7*49*2

We get,

686m^3
