Answer 2

Given
$Circumference = 154m \\ \: Circumference = 2\pi \: r \\ 2\pi \: r = 154 \\ so \: \\ r = \frac{154}{2\pi} \\ \\ r = \frac{77 \frac{}{?} }{ \frac{22}{7} } \\ \\ r = \frac{49}{2} \\ \\ r = 24.5m \\ \\ \\ now \: for \: area...... \\ \\ area = \pi \: {r}^{2} \\ \\ area = \frac{22}{7} \times \frac{49}{2} \\ \\ area = 77 {m}^{2}$

Hope it helps❤
