This angle is 144. Our calculators are very handy but we can find the arc length and the sector area manually. It will also calculate the area of the sector with that same central angle.

Our calculators are very handy but we can find the arc length and the sector area manually.

The arc length is first approximated using line segments which generates a Riemann sum. It will also calculate the area of the sector with that same central angle. Then divide the result by the radius squared make sure that the units are the same to get the central angle in radians. It spews out 25314.
