Actually I have solved it

k=S-3pis^2/3pi - Sep 10th 2011, 01:23 AMSironRe: Find k in the equation?
If the equation is:

$\displaystyle 3\pi\cdot s\cdot k+3\pi\cdot s^2=S$

$\displaystyle \Leftrightarrow 3\pi\cdot s\cdot k=S-3\pi\cdot s^2$

$\displaystyle \Leftrightarrow k=\frac{S-3\pi\cdot s^2}{3\pi\cdot s}$

You have forgotten a factor $\displaystyle s$ in the denominator.
