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

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

Four equal circles, each of radius 5cm, touch each other as shown in Figure. Find the area included between them.

Four equal circles, each of radius 5cm, touch each other as shown in Figure. Find the area included between them.

The equation of four circles are (x+-a)^2+(y+-a2=a^2 . The radius of a circle touching all the four circles is (sqrt(2)+2)a (b) 2sqrt(2)a (sqrt(2)+1)a (d) (2+sqrt(2))a

The circle with centre (2,3) touching x-axis has the radius equal to

If a circle of radius 2 touches X-axis at (1,0) then its centre may be

Circle touching both the axes and radius 5 is

The equation of the circle touching the coordinate axes the line x+2=0 is

A circle of radius 2 lies in the first quadrant and touches both the axes. Find the equation of the circle with centre at (6,5) and touching the above circle externally.
