If the measure of central angle aob is 62 degrees, what is the measure of inscribed angle acb?

arc length   =   circumference • [central angle (degrees) ÷ 360]

 where circumference   =   [2 • π • radius]

We are not given the radius so we'll say it is 1.

arc length = 2 * PI * radius * 62 / 360

arc length = 6.2831853072 * 1 * 0.1722222222

arc length = 1.0821041362 (where radius = 1)
