Question

Find the area of a circle of radius 50 cm.​

Answer 1

$\huge\underline {\sf{Solution \huge \rightarrow}}$

$\large\underline{\sf{given: radius \: of \: circle \rightarrow \: 50cm}}$

$\large\underline{\sf{to \: find \rightarrow area \: of \: circle}}$

___________________

$\large\underline{\sf{formula \: to \: find \: area \: of \: }}$

$\large\underline{\sf{circle \rightarrow \: \pi {r}^{2} }}$

____________________

$\large\underline{\sf{ area_{circle} \rightarrow \pi 50^{2} }}$

$\large\underline{\sf{area_{circle} \rightarrow \frac{22}{7} \times 2500}}$

$\large\underline{\sf{area_{circle} \rightarrow 7857.14 {cm}^{2} }}$
