    Answer: 60 in

    Step-by-step explanation:

    Hi, to answer this question, first we have to calculate the diameter of one flotation device:

    Circumference of a circle C = (3.14) (diameter)

    Replacing with the values given:

    62.8 = 3.14 d

    Solving for d (diameter)

    62.8 / 3.14 = d

    20in = d

    Now, since the three flotation devices are identical, we simply have to multiply the diameter of one device by 3, to obtain length of the flotation devices lined up.

    20x3 = 60 in

    Feel free to ask for more if needed or if you did not understand something.
