The formula for the circumference of a circle is:
C = 2(π)(r)

You are given the diameter (6), but need the radius. So to find the radius, just divide the diameter by 2.
6÷2 = 3

The radius is 3, so now you can plug this into the equation.
C = 2(π)(3)
C = 6(π)
C = 18.85
This can be rounded to 19 feet.

The answer is:
A. 19
