Answer 2

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Radius\:of\:circle=97.86\:units}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green {\underline \bold{Given : }} \\ \tt: \implies Circumference \: of \: circle = 615.44 \: units \\ \\ \red {\underline \bold{To \: Find : }} \\ \tt: \implies Radius \: of \: circle = ?$

• According to given question :

$\bold{As \: we \: know \: that} \\ \tt: {\implies Circumfererence \: of \: circle = 2\pi r} \\ \\ \tt: \implies 615.44 = 2 \times \frac{22}{7} \times r \\ \\ \tt: \implies 615.44 \times 7 = 44 \times r \\ \\ \tt: \implies r = \frac{615.44 \times 7}{44} \\ \\ \tt: \implies r = 13.98 \times 7 \\ \\ \green{\tt: \implies r = 97.86 \: units} \\ \\ \purple{ \bold{Some \: formula \: related \: to \: topic}} \\ \pink{ \tt\circ \: Area \: of \: circle = \pi {r}^{2} } \\ \\ \pink{ \tt\circ \: Perimeter \: of \: semicircle =\pi d} \\ \\ \pink{ \tt\circ \: Area \: of \:semicircle= \frac{1}{2} \pi {r}^{2} }$
