A circle with radius r is located in the first quadrant of the coordinate plane, so that it is tangent to both the x-axis and the y-axis. It is also tangent to the circle with center (3, 0) and radius 1. Find the sum of all possible values of r.
By the distance formula, the sum of all possible values of r is 6.
it wasnt 6
the answer was 8
Oh, you were right! The answer was 6!
