Answer: 18Pi

Step-by-step explanation:

The equation of the circumference of a circle is 2 x Pi x radius

The radius is one half of the diameter. So to find the radius we can divide the diameter by 2.


18 divided by 2 is 9

So to find the circumference we can just do Pi x 9 x 2

9 x 2 = 18

So the answer is 18Pi, or 56.52
