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?

π/72

π/60

π/36

π/30

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
