Answer 1

I hope this helps you

Answer 2

Answer with explanation:

The given equation which represents a circle having center at, (2,0) and radius =8 is,

 $(x - 2)^2 + y^2 = 64\\\\y^2=64 - (x-2)^2\\\\y^2=64 - (x^2-4 x +4)\\\\ y^2=64 -x^2+4 x-4\\\\y^2=60+4 x-x^2$

Result  of isolating y² in the equation below, gives

   Option A

            $y^2=60+4 x-x^2$
