PLEASE HELP. WILL GIVE BRAINLIEST FOR CORRECT ANSWER

Answer 1

Are of shaded region = area of circle - area of segment
$= \pi {r}^{2} - ((\alpha \div 360) \times \pi \times {r}^{2} )$
$= \pi {r}^{2} (1 - \alpha \div 360)$
$r = 8.35 \\ \alpha = 100$
$= 158.1666....$
$rounding \: up$
$area \: of \: shaded \: region \: = 158.2 \: \: square ft$
