In order to find the circumference, we first need to find the radius. We have the area, so we can find the radius. We set up this equation:


1519.76= \pi r^(2)

We begin by dividing both sides by pi.

483.76 =
r^(2)

Next, we take the square root of both sides to get the radius.

r = 22.

Next, we plug this into the formula for the circumference, 2 pi r


C = 2 \pi *22=138.23

So, the circumference of this circle is 138.23 units.
