In general, the equation of a circle is in the form:

$$x^2+y^2=r^2$$
Where x and y are your coordinates and r is the radius. Any translations in x or y (that is, any numbers added to or subtracted from x or y) only affect the position of the circle, but not its size, so the radius would be the same.

Based on your equation, what would the radius of that circle be?
