    The ferris wheel travelled 434.717 ft.

    Step-by-step explanation:

    Assuming that the ferris wheel is a perfect circle, then it's height is the same as the diameter of the circle, therefore it's radius is:

    radius = height/2 = 246/2 = 123 ft

    The distance travelled by the ferris wheel is the same as the length of the arc created by a angle of (9pi/8). The length of an arc is given by:

    length = r * (angle in radians)

    length = 123 * (9pi/8)

    length = 434.717 ft

    The ferris wheel travelled 434.717 ft.
