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

Answer:

704 kilolitres (3 s.f.)

Step-by-step 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.)
