A. calculate the ratio of the length of each arc to the circles circumference
1)the measure of ab is 40°
2)the measure of cd is 90°
b. calculate each arc length. write your answer in terms of π pi
1) if the measure of ab is 45° and the radius is 12 meters, what is the arc length of ab?
2) if the measure of cd is 120° and the radius is 15 centimeters, what is the arc length of cd?
c. calculate each arc length. write your answer in terms of pi.
1)if the measure of ab is 135° what is the arc length of ab?
2) if the measure of cd is 45° what is the arc length of cd?
