We know that the distance between the point (x, y) and origin (0, 0) can be found using the distance formula which is equal to√x 2 y 2= a Therefore, the equation of a circle, with the center as the origin is, x 2 y 2 = a 2 Where "a" is the radius of the circle Alternative Method Let us derive in another way Suppose (x,y) is a point on a circle, and the center of the circle isCenter (0,0) and radius 3 answer choices x 2 y 2 =3 x 2 y 2 =6 x2y2 =9 s Question 5 SURVEY
