Hi,

To find the volume of cylinder this formula is required.

[tex]v = \pi {r}^{2} h[/tex]

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

[tex]80 \div 2 = 40[/tex]

Now just put your values into formula.

[tex]v = \pi {40}^{2} \times 130 \\ v =653451.27[/tex]

You will need 653451.27 cubic centimetres of concrete.

Hope this helps.
