    1. The problem statement, all variables and given/known data
    The angular velocity of the ferris wheel with a diameter of 18m is pi/24 radians/s. How would that compare to m/s?

    2. Relevant equations
    v=(2pi(r))/360

    3. The attempt at a solution
    2pi(9)/360
    =0.157m/s

    You know the circumference and you should know how find how long it will take to make one revolution.
    Circumference (m)/ time for revolution (sec)= speed m/sec.

    it takes 0.8mins to make one revolution

    Right, so what do you get for speed in m/sec?

    would that be 1.178m/s?

    because 2pi(9m)/48s
