Answer:
10π/3 mm
Step-by-step explanation:
Arc length is:
s = rθ × π/180
where r is the radius and θ is the angle in degrees.
Here, r = 10 mm and θ = 60°.
s = (10) (60) (π/180)
s = 10π/3
Another way to calculate it is to find the entire circumference then divide by 6, since 60° is one-sixth of 360°.
