a) Determine the angular velocity in rad/s

b) A ride lasts 4 min. How far will a rider travel in 4 min?

My Work:

a) C = 2Pi(25 m) = 50Pi m

50Pi m / 25 m = 2Pi rad

2 rotations/min x 2Pi = 4Pi rad/min

Therefore the angular velocity is Pi / 15 rad/s

b) 4 x 4Pi = 16Pi

16Pi = a / 25 m

a = 25(16Pi)

a = 400Pi

a = 1256.6 m

I believe I am correct but I am hoping someone could check over my approach to the problem as my text was not very clear at all and I have tried to figure this out mainly on my own.
