In the adjoining figure , line PQ is a common tangent to the externally touching circles and the radii of two circles are 25cm and 9cm. Find the length of the common tangent segment of these circles.

Two circles of radius 4 and 3 cm are at some distance s.t. length of the transversal common tangent and length of direct common tangent are in the ratio 1 : 2 find the distance b/w centres

Given two circles intersecting orthogonally having the length of common chord (24)/(5) unit. The radius of one of the circles is 3 units. If length of direct common tangent is lamda units, then lamda^(2) is
