$$\mathrm{tan}\:\theta=\frac{\mathrm{13550}}{{r}} \\ $$$$\left(\mathrm{2}\pi−\mathrm{2}\theta\right){r}=\mathrm{13550} \\ $$$$\mathrm{2}\left(\pi−\theta\right){r}={r}\:\mathrm{tan}\:\theta \\ $$$$\mathrm{2}\left(\pi−\theta\right)=\mathrm{tan}\:\theta \\ $$$$\Rightarrow\theta=\mathrm{1}.\mathrm{305} \\ $$$$\Rightarrow{r}=\frac{\mathrm{13550}}{\mathrm{tan}\:\theta}\approx\mathrm{3689} \\ $$
