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

Dimensions of rectangular sheet of paper =` 44cm xx 20cm`
When this sheet of paper is rolled along its length, Circumference of base becomes =` 44 cm `
using the formula,
Circumference of base =` 2πr`
So,` 2pir = 44`
`2 xx 22/7 xx r = 44 `
` r=44xx7 / 44`
Radius = `7cm`
Height = `20 cm`
Volume `=pir^2 h=22/7xx7^2xx20`
`=3080 cm^3`.
