It depends on what measure you want: the angle subtended or the length of the curved segment, and also on what information you do have.

How do you find the measure of an arc knowing only the chord of arc and radius?

you have a triangle formed by the radius on 2 and the chord on the other. the angle in that triangle that is opposite the chord, find its measure in radians take that measure (in radians) and multiply it by the radius to get the arc length


How do you find the arc length with the angle given?

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.


Is arc length the same as arc measure?

No, arc measure is an ambiguous expression since it could also refer to the angular measure of the arc.
