    1257 ft.

    50 x 3.14 = 157.1

    8 x 157.1 = 1257

    1256 ft

    Step-by-step explanation:

    The circumference of a circle tell us how long is the line which enclose the circle. So, after 1 revolution a child seated near the outer edge travels a distance equal to the circumference of the carousel. If 8 revolutions are made the distance travelled will be 8 times the circumference.

    Circumference = π · diameter = π · 50 ft = 157 ft

    Distance travelled = 8 · 157 ft = 1256 ft
