Solve r=18cmpiapprox22/7

$$r = 18 cm \pi \approx \frac { 22 } { 7 }$$

Solve for c (complex solution)

$$\left\{\begin{matrix}c=\frac{r}{18\pi m}\text{, }&m\neq 0\\c\in \mathrm{C}\text{, }&r=0\text{ and }m=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$18cm\pi =r$$

The equation is in standard form.

$$18\pi mc=r$$

Divide both sides by 18m\pi .

$$\frac{18\pi mc}{18\pi m}=\frac{r}{18\pi m}$$

Dividing by 18m\pi undoes the multiplication by 18m\pi .

$$c=\frac{r}{18\pi m}$$

Solve for m (complex solution)

$$\left\{\begin{matrix}m=\frac{r}{18\pi c}\text{, }&c\neq 0\\m\in \mathrm{C}\text{, }&r=0\text{ and }c=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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