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
