Answer: An arc can be measured either in degree or in unit length. A

arc is a portion of the circumference of the circle which is

determined by the size of its corresponding central angle.

Explanation:

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)
