    94.2 inches.

    Step-by-step explanation:

    The length of the circle can be determined by

    length 'l' = 2πr

    l = 2 x 3.14 x 3 = 18.84 inches

    As the spinner and it travels completely around the circle 5 times, therefore, we'll have the distance of

    distance = l x 5

    distance = 18.84 x 5 = > 94.2 inches

    Thus, the tip of the spinner traveled 94.2 inches.

    The spinner travelled 94.2 inches.

    Step-by-step explanation:

    In order to solve this question we first need to calculate the length of the circle, that is given by the following formula:

    length = 2*pi*r

    length = 2*3.14*3 = 18.84 inches

    Since the spinner revolved around the circle 5 times, the distance travelled by the tip is the length of the circle multiplied by 5, as shown below:

    distance = length*5

    distance = 18.84*5 = 94.2 inches

    The spinner travelled 94.2 inches.
