The radius is the midpoint of a diameter.

The equation for a circle is:

$\left(x-(\text{x-value of the center})\right)^2$ $+\left(y-(\text{y-value of the center})\right)^2=\left(\text{the length of the radius}\right)^2$

So you need to find the coordinates of the center and the radius. Can you do the rest?

I can take it from here. I like your set up.
