Question

Hope someone can help me with this

Answer 1

Hi,

To find the volume of cylinder this formula is required.


`v = \pi {r}^(2) h`

To get radius you need to divide diameter with 2 like this.


`80 / 2 = 40`

Now just put your values into formula.


`v = \pi {40}^(2) * 130 \\ v =653451.27`

You will need 653451.27 cubic centimetres of concrete.

Hope this helps.
