Answer:
18.84 feet
Step-by-step explanation:
The circumference of a circle can be found using: 
c=π*d 
The radius is given, but we have to find diameter. The diameter is twice the radius, or 
d=2r 
The radius is 3 feet. Substitute 3 in for r. 
d=2*3 
d=6 
The diameter is 6 feet. 
Now we have the diameter. We can substitute 6 in for d in the circumference formula. We can also substitute 3.14 in for pi.
c=π*d 
c=3.14*6 
c=18.84
The circumference is <u>18.84 feet</u>
