Answer:
D) 16π/3 ft
Explanation:
We solve the above question using the Arc length formula when our central angle is in degrees
The formula is given as:
Arc length = 2πr × θ /360
r = 4 ft
θ = Central angle in degrees = 240°
Hence,
2 × π × 4 × 240/360
8π × 240/360
8π × 20/30
16π/3 ft
Arc length = 16π/3 ft
Option D is the correct option
