We can use this formula: C = 2 * $\pi$ * r
We can't use the diameter in this formula. We have to use the radius. And the radius is half of the diameter.

9 / 2 = 4.5

And we'll also use 3.14 for [tex] \pi [/text].

Plug in all the values:

C = 2 * 3.14 * 4.5
C = 28.26

So, the circumference is 28.26.

y ---> 5

Step-by-step explanation:

We are given paired values for two variables x and y and we are to determine the constant number by which each term is increased such that they are in a proportional relationship.

For x, we have the following paired values:

$x: 1, 2, 3, 4$
