Hlo friend.. Cutiepie Here..

Here is ur answer :



Length l of Rectangular sheet = 22 cm

Breadth b of Rectangular sheet = 10 cm

If it is fold along its length to form cylinder.

Then, the breadth of Rectangular sheet is height of cylinder.

Height h of cylinder = 10 cm

The length of rectangular sheet is circumference of the base.

Circumference of base = 22 cm

 2\pi r \:  = 22

r =  \frac{22}{2\pi}


r =  \frac{11}{\pi}  \: cm



Volume of cylinder :

 = \pi {r}^{2} h


 = \pi \times  \frac{11}{\pi}  \times  \frac{11}{\pi}  \times 10

\pi \:  \: cancel \:  \: out

Putting the value of /pi

 = 11\times  \frac{11}{ \frac{22}{7} }  \times 10


 = 11 \times 11 \times  \frac{7}{22} \times 10


 =11 \times  \frac{7}{2}  \times 10


 = 11 \times 7 \times 5


 = 385\:  \:  {cm}^{3}

HOPE IT HELPS YOU..
