Answer 1

$hey \\ \: \: \: \: here \: is \: your \: answer$

$area \: of \: circle \: = \pi \: {r}^{2} \\ \: \: \: \: \: \: 31.4 =3.14 \times {r}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \frac{31.4}{3.14} = \ {r}^{2} \\ \: \: \: \: \: \: 10 = {r }^{2} \\ \: \: \: \: \: \: \: \: r = \sqrt{10} \\ \: \: \: \: \: \: \: \: r = 3.16$
$thanks$
