    This is correct if you mean r=(k-h^2)/(pi)

    r=\frac{k-h^2}{\pi} [/tex]

    [edit] no e in pi... ;)

    This is incorrect: you have written [tex] r = K - \frac{h^2}{\pi}, [/tex] at least when read according to *standard rules*. If you mean that
    [tex] r = \frac{K - h^2}{\pi} ,[/tex] then you need to use brackets: r = (K - h^2)/pi.
