The circumference is 26
To find this we must start by finding the radius of the circle. You can find this using the formula for area adjusted to find the radius.
r =
Then when we plug the area in for A, we get the radius to be 13.
We can then use that number in the circumference formula which is below.
C = 2r
Using that we can find the circumference to be 26
