Sorry about the handwriting! For (i), complete the square to convert the given equation into a general equation for a circle. We can derive coordinates for the circle’s center and its radius directly. For (ii), simply compare areas for both circles. For (iii), create 2 simultaneous equations using the coordinates given and solve accordingly. Note that you need to find out where on the y axis the circle will intersect.
