A circle of radius 2 has its centre at (2,0) and another circle of radius 1 has its centre at (5, 0).A line is tangent to the two circles at point in the first quadrant.The y-intercept of the tangent line is

A circle can have .............parallel tangents at the most.

Two circle are externally tangent.Lines PAB and PA'B' are common tangents with A and A' on the smaller circle and B' and B' the on the larger circler circle and B=4 then the square of the radius of the circle is

Two circles are externally tangent.Lines PAB and PA'B' are common tangents with A and A' on the smaller circle B and B' on the larger circle.If PA=AB=4, then find the radius of smaller circle
