arc_length+=+%28n%2F180%29%2APi%2Ar
where n is measured in degrees
given:
arc_length=3Pi
r=6
n=+%28arc_length%2A180%29%2F%28Pi%2Ar%29
n=+3Pi+%2A180%2F%28+Pi%2A6%29
n=+3cross%28Pi%29+%2A180%2F+%28cross%28Pi%29%2A6%29
n=+3+%2A180%2F+6
n=+%28cross%283%29%2A180%29%2F%28cross%286%29%2A2%29
n=+180%2F2
n=+90
