A right circular cylinder has a height of ​ 2012 ​ ft and a diameter ​ 115 ​ times its height.

What is the volume of the cylinder?

Enter your answer in the box. Use 3.14 for pi and round only your final answer to the nearest hundredth.
Plz explain if you can.

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


r= (1)/(2) (115*2012)

This gives you


r=115,690

So now we can solve for the volume by using the substituted values in the original equation


V=(3.14)(115690)^(2)(2012)

which simplifies down to


8.455694166 x 10^(13)

so you could answer


V=8.46 * 10^(13)

or

84556941663448.00

I would recommend the one in scientific notation
