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

Four circles each with radius 2 touch both 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:

The two circles touch each other if

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

A circle with centre (h,k) .If the circle touches x -axis then the radius of the circle is

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:

Two circle , both of radii a , touch each other and each of them touches internally a circle of radius 2a , then the radiusof the circle which touches all the three circles is :
