$\large\bf\blue{circumferenc \: of \: circle = 2\pi \: r}$
$\large\bf\blue{44 = 2 \times \frac{22}{7} \times r}$
$\large\bf\blue{r = \frac{44 \times 7}{22 \times 2} }$
$\large\bf\blue{r = 7cm}$

$\large\bf\blue{area \: of \: circle \: = \pi {r}^{2} }$
$\large\bf\blue{ \frac{22}{7} \times {7}^{2}}$
$\large\bf\blue{ \frac{22}{7} \times 7 \times 7}$
$\large\bf\blue{22 \times 7}$
$\large\bf\blue{154 {cm}^{2}}$
