The circle class should have the folllowing (private) attributes and (public) methods: x coordinate (an int), can be negative y coordinate (an int), can be negative radius (a double), must be greater ...

frac{4}{3}\) The radius that joins the centre of the circle (0, 0) to the point P is at right angles to the tangent, so the gradient of the tangent is the negative reciprocal of the gradient of ...
