If radii of two circles are 4 and 3 and distance between centres is `sqrt(37)` then angle between the circles is

If radii are 2, sqrt(2) and distance between centres is sqrt(2) then the angle between the circle is

The radii of two circles are 4.5 cm and 3.5 cm respectively. The distance between the centres of the circles is 10 cm. What is the length of the transverse common tangent ?

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

The condition for two circles with radii and r_(1) and r_(2) be the distance between their centre,such that the circles are orthogonal is

Two circles touch internally.The sum of their areas is 170 pi cm and the distance between their centres is 4cm.Find the radii of the circles

Suppose we have two circles of radius 2 each in the plane such that the distance between their centres is 2sqrt3. The area of the region common to both circles lies between

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
