To move the windmill so that the blades can catch the wind there is a circle of stones used to anchor the windmill as it turns. The circle of rocks is at a distance of 1.5 meters from the base of the windmill. The equation of the circle that represents the rocks is x²+y²=49. Which circle is the best representation of the circle that models the circle of rocks?
