How long is the arc intersected by a central angle of 5 pi over 3 radians in a circle with a radius of 2 ft? Round your answer to the nearest tenth. Use 3 point 1 4 for pi

For an angle measured in radians, the arc length is s = rθ. Substituting the radius of 2 ft and the angle of 5π/3 gives s = 2(5 × 3.14 ÷ 3) ≈ 10.47 ft, which rounds to 10.5 ft. The correct choice is 10.5 ft.
