# What is the arc length when θ = pi over 3 and the radius is 5 cm?

**Solution:**

The length of an arc of a circle is the circumferential length of the curve called an arc.

Given:

Radius = 5 cm

Angle = π/3

To find: Arc length(A)

The formula of arc length is

A = radius × angle(in radian)

A = 5 × π/3

A = 5 × 3.14/3 (π = 3.14)

A = 15.70/3 = 5.23 cm

You can also calculate arc length using an arc length calculator.

Thus, 5.23 cm is the arc length when θ = pi over 3 and the radius is 5 cm.

## What is the arc length when θ = pi over 3 and the radius is 5 cm?

**Summary:**

5.23 cm is the arc length when θ = pi over 3 and the radius is 5 cm.
