# Circle A has a center at (9 ,-2 ) and a radius of 1 . Circle B has a center at (1 ,3 ) and a radius of 4 . Do the circles overlap? If not, what is the smallest distance between them?

Distance between the centers$= \sqrt{{\left(1 - 9\right)}^{2} + {\left(3 + 2\right)}^{2}}$
$= \sqrt{64 + 25} = \sqrt{89} = 9.434$
