Write the standard equation of the circle whose center is (-5,4) with a radius of  \frac{1}{2}  

 (𝑥5)2+(𝑦+4)2=14 (𝑥-5)^2+(𝑦+4)^2=\frac{\text{1}}{\text{4}}\   

 (𝑥+5)2+(𝑦4)2=14 (𝑥+5)^2+(𝑦−4)^2=\frac{\text{1}}{\text{4}}\   

 (𝑥+5)2+(𝑦4)2=12 (𝑥+5)^2+(𝑦−4)^2=\frac{\text{1}}{\text{2}}\   

 (𝑥5)2+(𝑦+4)2=12 (𝑥-5)^2+(𝑦+4)^2=\frac{\text{1}}{\text{2}}\

Find the equation of the circle whose center is C(5,9) and one of its diameter's endpoints is (0,0).


(Requires Solution)

(𝑥5)2+(𝑦9)2=106(𝑥−5)^2+(𝑦−9)^2=\sqrt{106}

(𝑥+5)2+(𝑦+9)2=106(𝑥+5)^2+(𝑦+9)^2=106

(𝑥5)2+(𝑦9)2=106(𝑥−5)^2+(𝑦−9)^2=106

(𝑥+5)2+(𝑦+9)2=106(𝑥+5)^2+(𝑦+9)^2=\sqrt{106}
