What is the distance between the centres of the two circles ?

Two circles of radius 4 units and 3 units are at some distance such that the length of the transverse common tangent and the length of their direct common tangent are in the ratio 1 : 2. What is the distance between the centres of those circles.

R and r are the radii of two circles (R > r). If the distance between the centres of the two circles be d, then length of common tangent of two circles is

R and r are the radius of two circles (R gt r) . If the distance between the centre of the two circles be d , then length of common tangent of two circles is

Consider two circle of radius 3 and 1 and distance between the centre of these two circle is 5, then length of external common tangent is

The distance between the centres of the two circles of radii r_1 and r_2 is d. They will thouch each other internally if

If two circles touch internally,then the distance between the centres of the circles is equal to the sum of their radii.

Two circles with equal radii are intersecting at the points (0, 1) and (0,-1). The tangent at the point (0,1) to one of the circles passes through the centre of the other circle. Then the distance between the centres of these circles is.
