v\geq 0
Solve for r (complex solution)
r=16v^{2}
arg(v)<\pi \text{ or }v=0
Solve for v (complex solution)
v=\frac{\sqrt{r}}{4}
Solve for v
v=\frac{\sqrt{r}}{4}
r\geq 0

\sqrt{\frac{r}{16}}=v
Swap sides so that all variable terms are on the left hand side.
\frac{1}{16}r=v^{2}
Square both sides of the equation.
\frac{\frac{1}{16}r}{\frac{1}{16}}=\frac{v^{2}}{\frac{1}{16}}
Multiply both sides by 16.
r=\frac{v^{2}}{\frac{1}{16}}
Dividing by \frac{1}{16} undoes the multiplication by \frac{1}{16}.
r=16v^{2}
Divide v^{2} by \frac{1}{16} by multiplying v^{2} by the reciprocal of \frac{1}{16}.
