the merry go round music box has a diameter of 12.5 inches. it is scale model of a HershchellSpillman Carousel which is 35 feet in diameter. A miniature horse 5.5 inchs from the center of the music box makes one complete rotation in 27 seconds. find the horse's angular speed in radians per second.Round your answer to the nearest hundredth.
(I cant figure out how to solve it what do i do to get the answer 0.23 radians or 2pi over 27)

Henry,
V = 1rev/27s,
1rev = 2pi radians.
Substitute 2pi radians for 1rev and get:
V = 2pi radians / 27s
V = 6.28 / 27 = 0.23rad/S
