If you are given two points (a,b) and (c,d)
the midpoint is ( (a+c)/2 , (b+d)/2 )
and the distance between them is √( (a-c)^2 + (b-d)^2 )

apply this to your data,
then let me know what you got for the equation of the circle.
the center is the midpoint of PQ

the radius is half the length of PQ

with (h,k) as the center, and r as the radius
... the circle equation is ... (x - h)^2 + (y - k)^2 = r^2
