Hi, 

C: (0,0) and the point (-4,6) lies on the circle

D = sqrt+%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29%29, r =sqrt%284%5E2+%2B+%28-6%29%5E2%29+=+sqrt%2852%29 

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 for this circle, in standard form: x%5E2+%2B+y%5E2+=+52
