Answer:

To calculate the circumference, or the length of the edge of the circle. You need to use the formula: 2πr = l.

π or pi is equal to about 3.14, so I'll use that number to solve this.

If the length of r is 3, than we plug in that number, along with 3.14 into the formula:

2 x 3.14 x 3 = l

Now you multiply:

2 x 3.14 = 6.28

6.28 x 3 = 18.84

So your final answer is: l(length) =  18.84 meters!
