The arc length of an angle on a circle can be found using the formula:
Arc Length = r × θ
Where r is the radius of the circle and θ is the angle in radians. For a unit circle, the radius r is 1.
In this case, the angle given is π/3 radians.
Substituting the values into the formula:
Arc Length = 1 × (π/3) = π/3
Therefore, the arc length of an angle of π/3 radians formed on the unit circle is π/3 units.
