Answer

Length of the arc = 33 ft.

Step-by-step explanation

The length of an arc is given as


\text{Length of an arc = }(\theta)/(360\degree)*2\pi r

where

θ = Angle subtended at the center of the circle by the arc = 210°

π = pi = (22/7)

r = radius of the circle = 9 ft.


\begin{gathered} \text{Length of an arc = }(\theta)/(360\degree)*2\pi r \\ \text{Length of an arc = }(210\degree)/(360\degree)*2*(22)/(7)*9=33\text{ ft.} \end{gathered}

Hope this Helps!!!
