Hello there!
Now, the formula to find the circumference of a circle is C = 2
r. Now, since the circumference is 18, all we have to do is to divide 18 by 2 to find the <em>radius!</em>
The radius of the circle is 9 cm, since 18/2 = 9. However, this is the radius. We need the diameter.
Multiply 9 by 2 to find the diameter. 9 · 2 = 18. So the answer is B. 18 centimeters.
Hope this helped!
