A flat, very thin table has a circular hole with radius 1 and a circular hole with radius 2. The distance between the centres of the two holes is 7. Two spheres, each with radius r, sit in the two holes, touching the table all around the circumference of the holes, such that the spheres are tangent to each other. Determine the value of r.
