Hi
D = sqrt+%28%28x1-x2%29%5E2%2B%28y1-y2%29%5E2%29%29
(9,10) and
(3,2) Diameter = sqrt+%28%286%29%5E2%2B%288%29%5E2%29%29= 10 |radius = 5
Midpoint ( %28x%5B1%5D+%2B+x%5B2%5D%29%2F2, %28y%5B1%5D+%2B+y%5B2%5D%29%2F2)
Midpoint Pt(6,6), the center of the circle
Standard Form of an Equation of a Circle is %28x-h%29%5E2+%2B+%28y-k%29%5E2+=+r%5E2
where Pt(h,k) is the center and r is the radius
equation of a circle (x-6)^2 + (y-6)^2 = 25
