Answer: C = 2 x π x 6 
Explanation:
Hi, to answer this question we have to calculate the circumference of the circular flower garden. 
Since it’s a circle we have to apply the next formula: 
Circumference: 2 x π x radius 
Replacing with the value given, the expression that represents this situation is: 
C = 2 x π x 6 
If we solve it: 
C= 37.69 feet
