How do you find the distance? Please explain the steps ><

A ball in a pinball machine moves 13
of the way through a circular groove that has radius 3 m. How far does
the ball travel?

a. 3.14 m
b. 360 m
c. 6.28 m
d. 0.69 m

  • Math -

    "moves 13 of the way" ???

    check your typing.

    whole rotation = 2π(3) = 6π

    take "whatever you mean" of that circumference.

    I think you meant 1/3 of the way, sooo
    circum = 6π = 18.85
    1/3 of that is 6.28 , one of the choices
