Answer:

The area of sector is
25.12 miles^2

Explanation:

Radius of circle = 4 miles

We are supposed to find the area of a sector bounded by a 180 arc


\theta = 180^(\circ)

Area of sector =
(\theta)/(360^(\circ)) \pi r^2

Area of sector =
(180^(\circ))/(360^(\circ)) * (22)/(7) * 4^2

Area of sector =
25.12 miles^2

Hence The area of sector is
25.12 miles^2
