Answer:

28.3 ft.

Explanation:

To find the circumference of a circle, multiply the diameter by pi.


c=\pi d (3.14*diameter)

3.14 is a common substitute for pi.

The diameter is 9 ft.

Now we can plug the numbers into the formula.


\pi d(3.14 * 9)=28.26

Therefore, the circumference of this circle is 28.26 ft.

28.26 ≈ 28.3
