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 length of the flotation devices?

Find the diameter by dividing the circumference by PI:

Diameter = 62.8 / 3.14 = 20 inches.

There are 3 lined up so multiply the diameter by 3:

20 x 3 = 60 inches. (5 feet)

admin for giving such valuable information through your article . your article is much more similar to   word unscramble tool because it also provides a lot of knowledge of vocabulary new words with its meanings.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
