Question

The water pipe has a radius of 5cm and a height of 7cm what volume of water does it take to fill a pipe?

Answer 1

`"550 cm"^3`

Explanation:

Volume of water = Volume of pipe

Pipe is in the form of cylinder. So, Volume of pipe is

`"V" = πr^2h`

`"V" = 22/cancel"7" × ("5 cm")^2 × cancel"7"\ "cm"`

`"V" = "550 cm"^3`
