It is true that the solution set of an equation of a circle is all of the points that lie in the circle
The equation of a circle is represented as:
(x - a)^2 + (y - b)^2 = r^2
Where:
Center = (a,b)
Radius = r
The points are represented by (x,y)
The (x,y) can take any value as long as it makes the equation (x - a)^2 + (y - b)^2 = r^2 to be true
Hence, it is true that the solution set of an equation of a circle is all of the points that lie in the circle
