    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?
