Cari nilai h
\left\{\begin{matrix}h=\frac{3v}{\pi r^{2}}\text{, }&r\neq 0\\h\in \mathrm{R}\text{, }&v=0\text{ and }r=0\end{matrix}\right,
Cari nilai r
\left\{\begin{matrix}r=\sqrt{\frac{3v}{\pi h}}\text{; }r=-\sqrt{\frac{3v}{\pi h}}\text{, }&\left(v\geq 0\text{ and }h>0\right)\text{ or }\left(v\leq 0\text{ and }h<0\right)\\r\in \mathrm{R}\text{, }&v=0\text{ and }h=0\end{matrix}\right,

\frac{1}{3}\pi r^{2}h=v
Tukarkan sisi sehingga semua suku variabel ada di sisi kiri.
\frac{\pi r^{2}}{3}h=v
Persamaan berada dalam bentuk standar.
\frac{3\times \frac{\pi r^{2}}{3}h}{\pi r^{2}}=\frac{3v}{\pi r^{2}}
Bagi kedua sisi dengan \frac{1}{3}\pi r^{2}.
h=\frac{3v}{\pi r^{2}}
Membagi dengan \frac{1}{3}\pi r^{2} membatalkan perkalian dengan \frac{1}{3}\pi r^{2}.
