Answer:

4.67 ft

Step-by-step explanation:

An arc is simply a portion of the circumference of a circle.

To find the length of an arc, we simply need to apply the formula:

[tex]L = \frac{\alpha }{360} * 2\pi r[/tex]

where α = angle subtended by the arc = [tex]\frac{2\pi }{3}[/tex] rads = [tex]\frac{2\pi }{3} * \frac{180}{\pi }[/tex] degrees = 38.2°

r = radius of the circle = 7 ft

Hence, the length of the arc is:

[tex]L = \frac{38.2}{360} * 2*\pi *7[/tex]

[tex]L = 4.67 ft[/tex]

The length of the arc is 4.67 ft
