A rectangular paper of width 14 cm is rolled along its width and a cylinder of radius 20 cm is formed. Find the volume of the cylinder (Fig 11.45)? (Take

Explanation

A rectangular paper of width `14 cm` is rolled along its width to form a cylinder.
Height of cylinder`=`width of rectangular paper `h=14cm`
Radius of cylinder `r=20 cm`
Volume of the cylinder`=pir^2h=22/7xx20xx20xx14=17600cm^3`
`therefore` Volume of the cylinder`=17600cm^2`
