Answer: c. 6.3 ft
Explanation:
Since, the length or an arc = [tex]r\times \theta[/tex] , where r is the radius of the circle, and [tex]\theta[/tex] is the central angle made by the arc.
Here, radius of the circle = 6 ft.
And,[tex]\theta= \frac{\pi}{3}[/tex]
Thus, the length of the arc= [tex]6\times \frac{\pi}{3}[/tex] = [tex]6\times\frac{22}{21}[/tex] = 6.28571429 ≈6.3 ft
