5-10 - Length of a Circular Arc These exercises involve the for- mula for the length of a circular arce. 5. Find the length of an are of a circle of radius 10 m if the are subtends a central angle of 27/5 rad. 6. A central angle 0 in a circle of radius 2.5 cm is subtended by an arc of length 7 cm. Find the measure of 0 in degrees and radians. 7. A circular arc of length 25 ft subtends a central angle of 50°. Find the radius of the circle. 8. A circular arc of length 137 m subtends a central angle of 130°. Find the radius of the circle. 9. How many revolutions will a car wheel of diameter 28 in. make over a period of half an hour if the car is traveling at 60 mi/h? 10. New York and Los Angeles are 2450 mi apart. Find the angle that the arc between these two cities subtends at the center of the earth. (The radius of the earth is 3960 mi.)
