Hi,

(2,3) and 

(-6,-5)  C(-2, -1)        Midpoint Pt(x,y):  ( %28x%5B1%5D+%2B+x%5B2%5D%29%2F2, %28y%5B1%5D+%2B+y%5B2%5D%29%2F2++%29)

D = sqrt+%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29%29

r =+%281%2F2%29sqrt%288%5E2+%2B+8%5E2%29 = 11.3/2 = 5.65

%28x%2B2%29%5E2+%2B+%28y+%2B+1%29%5E2+=+5.65%5E2
