The circumference of a circle is PiD, or 2(3.14)(r).

The radius is half the diamater.
Let's solve with the diameter.

18 • 3.14 = 56.52 inches.

I hope this helps!

The answer is below

Step-by-step explanation:

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given as:

$z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score,\mu=mean\ and\ \sigma=standard\ deviation \\\\For\ a\ sample\ size\ n: \\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }$
