Four circles each with radius 2 touch both the axes then the radius of the largest circle touching all the four circles is

Four circles each with radius 2 touches the axes, then the radius of the largest circle touching all the four circles, is

There are four circles each of radius 1 unit touching both the axis. The equation of the smaller circle touching all these circle is

Three equal circles each of radius r touch one another.The radius of the circle touching all the three given circles internally is (2+sqrt(3))r(b)((2+sqrt(3)))/(sqrt(3))r((2-sqrt(3)))/(sqrt(3))r(d)(2-sqrt(3))r

Three equal circles of radius unity touches one another.Radius of the circle touching all the three circles is:

If the four equal circles of radius 3 cm touch each other externally, then the area of the region bounded by the four circles is

The circles having radii 1,2,3, touch each other externally then find the radius of the circle which cuts the three circles orthogonally

Two circles of unit radius touch each other and each of them touches internally touches a circle of radius two.Then the radius of the circle which touches all the three circles is:
