Answer:
28.3 ft.
Step-by-step explanation:
To find the circumference of a circle, multiply the diameter by pi.
[tex]c=\pi d (3.14*diameter)[/tex]
3.14 is a common substitute for pi.
The diameter is 9 ft.
Now we can plug the numbers into the formula.
[tex]\pi d(3.14 * 9)=28.26[/tex]
Therefore, the circumference of this circle is 28.26 ft.
28.26 ≈ 28.3
