WebAnd it works out for every ratio. a tenth of the circumference will have a tenth of the angle. 1/pi of the circumference will have 1/pi of the angle. Now, for this, the circumference is 2pir by defenition And the angle is 2 radians. Of course the full angle all the way around is 2pi. So if we call the arc length S that gives us S/ (2pir) = 2/2pi.
