The circles overlap
Explanation:
Find the distance between the centres of the circles .
The distance between the x co-ordinates is 9 . The distance between the y co-ordinates is 6. ( if you are not sure about this sketch the points on a graph)
So the distance between the centres is
This is less than than 6+5 so the circles overlap..
