Answer 1

Dear Student,

$$\begin{gathered} \mathrm{The}\mathrm{diameter}\mathrm{of}\mathrm{largest}\mathrm{circle}\mathrm{will}\mathrm{be}\mathrm{equal}\mathrm{to}\mathrm{the}\mathrm{side}\mathrm{of}\mathrm{the}\mathrm{square}=10\mathrm{cm} \\ \mathrm{Radius}=\frac{\mathrm{diameter}}{2}=\frac{10}{2}=5\mathrm{cm} \\ \mathrm{circumference}=2\mathrm{\pi r} \\ =2\times \frac{22}{7}\times 5 \\ =\frac{220}{7} \\ =31.428\mathrm{cm} \end{gathered}$$
