Circle A has a center at #(4 ,-1 )# and a radius of #1 #. Circle B has a center at #(-3 ,2 )# and a radius of #3 #. Do the circles overlap? If not, what is the smallest distance between them?
I have just answered the same question but with different values. Have a look at https://tutor.hix.ai for the method

To determine if the circles overlap, we can calculate the distance between their centers and compare it to the sum of their radii. If the distance between the centers is less than the sum of their radii, then the circles overlap. Otherwise, they do not overlap, and the smallest distance between them is the difference between the distance between their centers and the sum of their radii.
Let's denote the centers of the circles A and B as ((x_1, y_1)) and ((x_2, y_2)) respectively, and their radii as (r_1) and (r_2) respectively.
For circle A:
Center coordinates: ((4, -1))
Radius: (r_1 = 1)
For circle B:
Center coordinates: ((-3, 2))
Radius: (r_2 = 3)
Using the distance formula, the distance between the centers is calculated as:
[ \text{Distance} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} ]
Substituting the given values:
[ \text{Distance} = \sqrt{(-3 - 4)^2 + (2 - (-1))^2} ] [ \text{Distance} = \sqrt{(-7)^2 + (3)^2} ] [ \text{Distance} = \sqrt{49 + 9} ] [ \text{Distance} = \sqrt{58} ]
Now, we compare the distance to the sum of the radii:
[ \text{Sum of radii} = r_1 + r_2 = 1 + 3 = 4 ]
Since ( \sqrt{58} ) is greater than 4, the circles do not overlap. The smallest distance between them is the difference between the distance between their centers and the sum of their radii:
[ \text{Smallest distance} = \text{Distance} - \text{Sum of radii} = \sqrt{58} - 4 ]
