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:
We begin by dividing both sides by pi.
483.76 =
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
So, the circumference of this circle is 138.23 units.
