The circumference of the base of a cylinder is 132 cm and its height 25cm. Find the volume of the cylinder.

Explanation

Let the radius of the cylinder be `r`.
Height of the cylinder `h=25cm`
Circumference`=132 cm`
`2pir=132 cm`
`2xx22/7xxr=132 cm`
`r=(132xx7)/2×22`
`r=21 cm`
Volume of a cylinder
`=pir^2h`
`=22/7xx(21)^2xx25`
`=22/7xx21xx21xx25`
`=34650 cm^3`
`therefore` The volume of the cylinder`=34650 cm^3`
