# Liquid Level of Horizontal Tank

Hello,

I want to calculate the liquid level of a horizontal cylindrical tank. Consider the equation :

V=L{(Pi)R^2-R^2ArcCos[(R-h)/R]+(R-h)Sqrt(2Rh-h^2)}

V=Tank volume

L= Tank length

R= Tank radius

h= Distance from top of tank to surface of liquid

What I want to do is to rearrange the above equation so that h is the subject. can this be done?

## Impossibleng makuha ang $h$.

Impossibleng makuha ang $h$. Nabuhol kasi sa $\arccos\left( \frac{R-h}{R} \right)$ at sa $\sqrt{2Rh-h^2}$.....hehehehehhe
