In the below figure PQ is a transverse common tangent of two circles with centers S and T such that PT:SQ=4:3 and
(RT-TP)/(RS+QS) = 8/9. It is also known that the length of the transverse tangent is 7sqrt6 cm Q1. Find the radius of the circle with center at T? Q2. Find the distance between the center of the two circles? Q3. Find the radius of the smaller circle? Q4. What 'll be the length of the other tangent drawn from Q to the circle with center at T? |
