Answer:
3.14 units
Explanation:
The formula for the length of an arc is ...
s = rθ
where r is the radius of the circle, and θ is the central angle in radians.
__
The relationship between degrees and radians is ...
180° = π radians
If we divide this equation by 3, we see ...
60° = π/3 radians
__
The radius is given as 3 units, so the arc length is ...
s = (3 units)(π/3) = π units
The arc length is 3.14 units.
