A rectangular sheet of paper, `44 cm xx 20 cm ,` is rolled along its length of form a cylinder. Find the volume of the cylinder so formed.

Explanation

Given that
length of the rect.=`44cm`
Breath of the rect.=`20cm`
Now since it has been rolled along its
length,therefore
`h `of the cylinder =`20cm`
Circumference=`44=2pir`
`22= 22/7 xx r`
`r =7 cm`
According to the question,
Volume of the cylinder=` pir^2h`
` 22/7 xx 7 xx 7 xx 20`
`3080cm^3`
