find the length of the arc intercepted by a central angle of 35 degree 28' in a circle of radius 15ft....i cant figure out how to get it ??

• Math trig. -

C = 2pi*r = 6.28 * 15 = 94.2 Ft. =
Circumference = Total distance around the circle. The intercepted arc is a fraction of that distance:

L = (35.47/360) * 94.2 = 9.28 Ft.
