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.
