Question

The radius of a cylindrical tank 4 m high is 14 How many kilolitres of water can be stored in the tank?(22/7)​

Answer 1

704 kilolitres (3 s.f.)

Explanation:

First, we'll work out the volume of the cylinder tank in
`m^3`.

`V_(cylinder)=\pi r^2h\\=\pi*4^2*14\\=224\pi (m^3)`

Then, we'll convert this into kilolitres.

We know that 1 cubic metre is 1 kilolitre.

So
`224\pi` cubic metres is approximately 704 kilolitres (3 s.f.)
