Answer:
(16/3)π ft
Step-by-step explanation:
The arc length formula is s = rФ, where Ф is the central angle in radians.
Here the central angle is 60° so we must convert this to radians:
60° π π
----- * -------- = ----- radians
1 180° 3
Thus, the arc length of interest is s = (16 ft)(π/3 rad) = (16/3)π ft
