34.54

Step-by-step explanation:

So the first thing you need to know is that to find the circumference of a circle is to use the formula 2 Pi R. R=Radius and to get the radius of a circle,  the problem will either tell you or it will give you a diameter (11 inches). Divide the diameter by 2 and you will get 5.5. But if the radius is 5.5 then you multiply that by 2, you will get back to 11 inches. So the last step is to do 11 x 3.14 and you get 34.54.
