Answer 1

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

$\green{\tt{\therefore{Diameter\:of\:circle\approx360.66\:cm}}}$

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

$\green{\underline \bold{Given:}} \\ \tt: \implies Circumference \: of \: circle = 1133.541 \\ \\ \red{\underline \bold{To \: Find:}} \\ \tt: \implies Diameter \: of \: circle = ?$

• According to given question :

$\bold{As \: we \: know \: that} \\ \tt: \implies Circumference \: of \: circle =1133.541 \\ \\ \tt: \implies 2\pi r = 1133.541 \\ \\ \tt: \implies r = \frac{1133.541}{2 \times \frac{22}{7} } \\ \\ \tt: \implies r = \frac{1133.541 \times 7}{2 \times 22} \\ \\ \tt: \implies r \approx 180.33 \: cm \\ \\ \green{\tt{\therefore Diameter \:of \: circle \approx360.66 \: cm}} \\ \\ \purple{\bold{Some \: formula \: related \: to \: this \: topic}} \\ \pink{\tt\circ \: Area \: of \: circle = \pi {r}^{2} } \\ \\ \pink{\tt\circ \: Area \: of \: semicircle = \frac{\pi {r}^{2} }{2} }$
