An arc can be measured either in degree or in unit length. An arc is a portion of the circumference of the circle which is determined by the size of its corresponding central angle. We create a proportion that compares the arc to the whole circle first in degree measure and then in unit length. (measure of central angle/360 degrees) = (arc length/circumference) arc length = (measure of central angle/360 degrees)(circumference) But, maybe the angle that determines the arc in your problem is not a central angle. In such a case, find the arc measure in degree, and then write the proportion to find the arc length.
The measure of the angle is the number of degrees in this case.

The angle measure is: 90.01 degrees
Multiply the radius by 2 and then by 3.14. Divide the length of the arc by this answer. Multiply this fraction by 360 degrees. That will be your answer.
