# What is the arc length of an angle of π/3 radians formed on the unit circle?

**Solution: **

Given: Angle (θ) = π/3 radians

We know that the arc length formula in radians can be expressed as arc length = θ × r

Where θ = Central angle of Arc, r = Radius of the circle

r = 1 [ Unit circle]

Thus,

Substituting the values of r and θ in the formula,

Arc length = θ × r

Arc length = π/3 × 1

= π/3

Hence, the arc length of an angle of π/3 radians formed on the unit circle is π/3.

## What is the arc length of an angle of π/3 radians formed on the unit circle?

**Summary:**

The arc length of an angle of π/3 radians formed on the unit circle is π/3.
