Hieght of a volume in a cylinder on its side, with known volume.

[GeorgeWBush]

This is my first post and is for an applied project (not for a class) but I thought this was the best place to ask for help.

Homework Statement

Given a cylindar on its side, with volume V, length L, and Radius R, what is height (h) of liquid. I have fomula for volume as a function of radius, length, and height, but when I try to solve for h, things get difficult.

The Attempt at a Solution

1) divide both sides by L
2) square both sides
3) expand polynomials
4) get stuck, post this message

Did you come up with that formula or was it provided and you have to solve for h?

\cos^{-1}(\frac{R-h}{R})=\frac{\mbox{adjacent}}{\mbox{hypotenuse}}

It was provided for me and I'm trying to solve for h. It is possible that there is a different approach to the problem that solves for h directly (via caluclus) but I have not found it.
