    How to solve for "x" in this equation

    Thanks in advance:

    here is my equation:

    Area = [itex]\pi[/itex]r[itex]^{2}[/itex] - r[itex]^{2}[/itex](arcos((r-x)/r))+(r-x))*[itex]\sqrt{2*r*x-x^{2}}[/itex]

    Is this related to the question you asked in another thread about the height of a liquid in a horizontal, cylindrical tank?

    If so, I don't think you can solve the equation above analytically for x. The best you can do is solve it numerically using some approximation technique.
