A central angle of a circle whose radius is 14 centimeters subtends an arc whose length is 7π15 centimeters.
What is the radian measure of the central angle?
i think its pi/30 ?
I think you meant 7pi /15 rahter than 7 pi 15 ?
Total circle circumference would be pi d = 28 pi
this arc is a fraction of the total
7 pi/15 / 28 pi x 2pi = pi/30 R
