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.

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.  

b) the dogs need to shift their focus to human scent.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
