In a rotated x'y' system, the equation x^2 + y^2 = r^2 represents a circle centered at the origin (0,0) with a radius of r. The equation remains the same regardless of the rotation of the coordinate system. The only difference is that the x and y coordinates are now measured with respect to the new axes x' and y'.
