the equation would be
V= \pi r^{2} h[/tex]
so if you substitute, you'd have to solve for the radius, which can be found by doing
[tex]r= \frac{1}{2} (115*2012)[/tex]
This gives you
[tex]r=115,690[/tex]
So now we can solve for the volume by using the substituted values in the original equation
[tex]V=(3.14)(115690)^{2}(2012)[/tex]
which simplifies down to
[tex]8.455694166 x 10^{13}[/tex]
so you could answer
[tex]V=8.46 * 10^{13}[/tex]
or
84556941663448.00
I would recommend the one in scientific notation
