The formula for an arc length is, S = rθ, where r is radius and θ is theta. Theta must be in radians (which it is because you stated theta = 4 pi / 7). Multiply 5 and 4 pi / 7, the arc length will be 20 pi / 7. It will be 8.97 when you compute this into a calculator (rounded to the nearest hundredth). Found this helpful? Give it a Brainiest award.
