Answer 1

Step-by-step explanation:

$given \: \\ the \: area \: of \: circle = 98.56 \\ \pi {r}^{2} = 98.56 \\ \frac{22}{7} \times {r}^{2} = 98.56 \\ {r }^{2} = \frac{98.56 \times 7}{22} = 31.36 \\ r = \sqrt{31.36} = 5.6cm \\ now \: \\ \: circumference \: of \: circle \\ = 2 \times \frac{22}{7} \times 5.6 \\ = 35.2cm$
