Which arc has the longer radius, an arc with a length of 16π with central angle 2π/3, or an arc with a length of 12π with central angle 4π/5? Explain.

-The second arc has a longer radius because the ratio of the central angle to the arc length is greater.

-The first arc has a longer radius because it has the greater arc length.

-The first arc has a longer radius because the ratio of the arc length to the central angle is greater.

-The second arc has a longer radius because it has the greater central angle.

s = rθ, so compare
(16π) / (2π/3) and (12π)/(4π/5)
