The Attempt at a Solution

r=K-h^2/pie

 

[ArcanaNoir]

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

$$r=\frac{k-h^2}{\pi}$$

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

solve for r: h^2+(pie)r=K

The Attempt at a Solution

r=K-h^2/pie

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