Math, circumference?

Question

Two points on the circumference of circle are A(4,5) and B

(-8,-6). Determine the coordinates of the centre of the circle and the circles radius.

Answer 1

As far as I can tell, you can't solve this with the information provided.  There is an almost infinite number of circles that could be drawn using those two points- and all of them would be correct answers.

If there is any other information hiding in the question, try applying it with this web page (it explains things pretty well): http://mathforum.org/dr.math/faq/faq.cir...
