To determine if the circles overlap, we need to find the distance between their centers and compare it to the sum of their radii. If the distance between the centers is greater than the sum of their radii, then the circles do not overlap. Otherwise, they overlap.
The distance between two points and is given by the formula:
Let's calculate the distance between the centers of Circle A and Circle B :
The sum of the radii of Circle A and Circle B is .
Since , the circles do not overlap.
To find the smallest distance between the circles, we subtract the sum of their radii from the distance between their centers:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
