A full 360 degree angle has an associated arc length equal to the circumference C So 360 degrees corresponds to an arc length C 2p R Divide by 360 to find the arc length for one degree. Hence the arc length is equal to radius multiplied by the central angle in radians. L 1 2b2 16a2 b2 8 a ln4 a b2 16a2 b L 1 2 b 2 16 a 2 b 2 8 a ln 4 a b 2 16 a 2 b.
