I'm having real trouble with maths. I missed the class and my books are really confusing. I've had a bash but I think my answer is really wrong. Can someone check it and tell me if i'm wrong. If so PLEASE include the theory not necessarily the answer so I can learn!
Thank you x

Q: A wheel is turning at 200 rev/min. Express this angular velocity in:
a) deg/s
b) rad/s LEAVING π IN THE ANSWER

My answer:
a) I did this two ways and still came to the same answer of 1200 degrees.
b) I got very confused here and came out with an obscure 100π/30

HELP!
