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:
[tex]1519.76= \pi r^{2} [/tex]
We begin by dividing both sides by pi.
483.76 = [tex] r^{2} [/tex]
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
[tex]C = 2 \pi *22=138.23[/tex]
So, the circumference of this circle is 138.23 units.
