Hi

Midpoint ( %28x%5B1%5D+%2B+x%5B2%5D%29%2F2, %28y%5B1%5D+%2B+y%5B2%5D%29%2F2)

(-4,6) to 

(8,-2)

Midpoint is (2,2) r = sqrt%286%5E2+%2B+4%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

Circle: (x-2)^2 + (y-2)^2 = 52
