Although you should by now notice there is going to be a problem, let's continue...


The form of a circle centered at (h,k) with radius r, is
and we have .
This circle has a radius of 2i (2 times the imaginary unit).
This is probably NOT what you wanted. Check your post carefully
for accuracy and re-post with corrections or clarification.
