Answer
Length of the arc = 33 ft.
Explanation
The length of an arc is given as
[tex]\text{Length of an arc = }\frac{\theta}{360\degree}\times2\pi r[/tex]
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.
[tex]\begin{gathered} \text{Length of an arc = }\frac{\theta}{360\degree}\times2\pi r \\ \text{Length of an arc = }\frac{210\degree}{360\degree}\times2\times\frac{22}{7}\times9=33\text{ ft.} \end{gathered}[/tex]
Hope this Helps!!!
