The circumference of the flotation device above is 62.8 inches. If three flotation devices are lined up end-to-end, then what is the lengh of the flotation devices.

Circumference of a circle C = (3.14) (d) Hint: Calculate the diameter for one flotation device. There are three floating devices.

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
