Assuming you want to know the circumference, we are given the area is $88\pi.$
Now we have to take it and set it equal to the area of a circle's equation.
$r^2\pi = 88\pi\\\implies r^2=88\\\implies r=\sqrt {88}\\\implies r=2\sqrt {22}$
The crcumference of a circle is $2\pi\cdot r\\\implies \boxed {4\sqrt{88}\pi}$
