| − | Two circles <math>C_1</math> and <math>C_2</math>, each of unit radius, have centers <math>A_1</math> and <math>A_2</math> such that <math>A_1A_2=6</math>. Let <math>P</math> be the midpoint of <math>A_1A_2</math> and let <math>C_#</math> be a circle externally tangent to both <math>C_1</math> and <math>C_2</math>. <math>C_1</math> and <math>C_3</math> have a common tangent that passes through <math>P</math>. If this tangent is also a common tangent to <math>C_2</math> and <math>C_1</math>, find the radius of circle <math>C_3</math>.
