Question

The circumference of a circle is 77 cm. Find its area.(write the formulaes for good explanation of the question)

Answer 1

$$\begin{gathered} DearStudent \\ Given \\ Circumference=2\mathrm{\pi r}=77\mathrm{cm} \\ \mathrm{therefore}\mathrm{radius}\mathrm{r}=\frac{77}{2\mathrm{\pi }}=12.25\mathrm{cm} \\ \mathrm{Now}, \\ \mathrm{Area}={\mathrm{\pi r}}^2=\mathrm{\pi }\times (12.25{)}^2=471.43{\mathrm{cm}}^2 \\ \mathrm{Regards} \end{gathered}$$
