Solve operatorname{circ}=36n

$$\operatorname { circ } = 36 n$$

Solve for n

$$n=\frac{irc^{2}}{36}$$

Steps for Solving Linear Equation

Multiply c and c to get c^{2}.

$$c^{2}ir=36n$$

Swap sides so that all variable terms are on the left hand side.

$$36n=c^{2}ir$$

The equation is in standard form.

$$36n=irc^{2}$$

Divide both sides by 36.

$$\frac{36n}{36}=\frac{irc^{2}}{36}$$

Dividing by 36 undoes the multiplication by 36.

$$n=\frac{irc^{2}}{36}$$

Solve for c

$$\left\{\begin{matrix}c=\left(-3+3i\right)r^{-\frac{1}{2}}\sqrt{2n}\text{; }c=\left(3-3i\right)r^{-\frac{1}{2}}\sqrt{2n}\text{, }&r\neq 0\\c\in \mathrm{C}\text{, }&n=0\text{ and }r=0\end{matrix}\right.$$
