The circumference is 26[tex] \pi [/tex]
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 = [tex] \sqrt{ \frac{A}{ \pi }} [/tex]
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 = 2[tex] \pi [/tex]r
Using that we can find the circumference to be 26[tex] \pi [/tex]
