Answer 1

Dear Student,
$$\begin{gathered} Areaofcircle={\mathrm{\pi r}}^2 \\ \mathrm{Perimeter}\mathrm{of}\mathrm{circle}=2\mathrm{\pi r} \\ \mathrm{Given}: \\ \mathrm{Area}\mathrm{of}\mathrm{circle}=\mathrm{Perimeter}\mathrm{of}\mathrm{circle} \\ {\mathrm{\pi r}}^2=2\mathrm{\pi r} \\ \boxed{\mathbf{r}\mathbf{=}\mathbf{2}\mathbf{}\mathbf{unit}} \end{gathered}$$
