The volume of a solid cylinder is `448\ pic m^3` and height 7cm. Find its lateral surface area and total surface area.

Explanation

Height, `h=7cm`

Volume of a cylinder, `V=pir^2h`

`448pi=pir^27`

`r^2=64`

`r=8cm`

C.S.A of cylinder = `2pirh`

C.S.A of cylinder = `2xx22/7xx8xx7`

C.S.A of cylinder = `352cm^2`
