The length of the arc is 4π.

<u>Step-by-step explanation</u>:

Given,

Diameter = 24 ft
radius, r = diameter/2
r = 24/2 = 12 ft
central angle, ∅ = 60°

Arc length = ∅/360° (2πr)

⇒ 60°/360° (2π $\times$ 12)

⇒ 24π/6

⇒ 4π

∴ The length of the arc is 4π.

Step-by-step explanation:

x * z = y

4 * z = 16

z = 16/4

z = 4
