The length of an arc subtended by a central angle is proportional to the circle's circumference. If the given central angle has measure
and the circle has radius
, then the arc has length
such that

where
is given in radians. Then

If
is given in degrees, then

-A terminating decimal is a decimal that NEVER ends
1/15 = 0.666666666.....
Therefore, 1/15 is a terminating decimal.
The period will be the length for one cycle of the function.
