Answer 2

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \red{ \: \: ANSWER \: \: } \mid}}}}}$

$\bold{ \sqrt{ \frac{Area}{\pi} } = \underline{ \: \: r \: (radius )\: \: }\: \: of \: \: a \: \: circle }$

$\bold{\underline{\: \: We \: \: know \: \: that \: \: }} \\ \\ \bold{Area \: \: of \: \: a \: \: circle \: = \pi \: r {}^{2} \: \: \: } \\ \\ \bold{ where ,\: \: \: r = Radius \: \: of \: \: the \: \: circle .\: }$

$\bold{ Now, \: } \\ \\ \: \: \: \: \: \bold{ \sqrt{ \frac{Area}{\pi} }} \\ \\ \bold{ = \sqrt{ \frac{\pi \: r {}^{2} }{\pi}} } \\ \\ \bold{ = \sqrt{ \frac{ \cancel{\pi} \: r {}^{2} }{ \cancel{\pi}} } } \\ \\ \bold{ = \sqrt{r {}^{2} } } \\ \\ = \bold{r}$
