Dado el C(-3,5) y radio r=4. La ecuacion ordinaria de la circunferencia es:

 (x+3)2(y5)2=16\left(x+3\right)^2-\left(y-5\right)^2=16  

 (x+3)2+(y5)2=16\left(x+3\right)^2+\left(y-5\right)^2=16  

 (x+3)2+(y5)2=8\left(x+3\right)^2+\left(y-5\right)^2=8  

 (x3)2(y5)2=42\left(x-3\right)^2-\left(y-5\right)^2=4^2
