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.

Text Solution

Verified by Experts

rectangular strip is rolled along the length so it looks like a cylinder
whose circumference`=44cm`
`2pir=44`
`r=7cm`and height `=20cm`
so volume of this cylinder `=pixxr^2xxh`
`=pixx7^2xx20`
`=3080cm^3`
