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

[davie08]

1. The problem statement, all variables and given/known data

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

2. Relevant equations

not sure

3. 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... ;)

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.
