*[tex \LARGE \ \ \ \ \ \ \ \ \ \ V_{cyl}\ =\ \pi{r^2}h]


Only knowing the volume doesn&#39;t help you much.  You could have a very short cylinder with a huge radius, or a very tall cylinder with a small radius, or anywhere in between and this infinity of cylinders would all have the same volume.


Your other problem is that 500 km is a linear distance, not a volume.  Volumes are expressed in cubic units.  You need to go back to the drawing board on this one.

My calculator said it, I believe it, that settles it
