What is the arc length if θ = 2 pi over 3 and the radius is 4 cm?

Solution:

The length of the arc is S = r × θ.

Given,

θ = 2𝜋/3

Radius, r = 4cm

Substituting these values in the formula

Arc length, S = 4 × 2𝜋/3

S = 8𝜋/3 cm

Therefore, arc length is 8𝜋/3 cm.

What is the arc length if θ = 2 pi over 3 and the radius is 4 cm?

Summary:

The arc length if θ = 2 pi over 3 and the radius is 4 cm is 8𝜋/3 cm.
