`C_1` is a circle of radius 1 touching the x- and the y-axis. `C_2` is another circle of radius greater than 1 and touching the axes as well as the circle `C_1` . Then the radius of `C_2` is `3-2sqrt(2)` (b) `3+2sqrt(2)` `3+2sqrt(3)` (d) none of these

C_(1) is a circle of radius 2 touching X-axis and Y-axis. C_(2) is another circle of radius greater than 2 and touching the axes as well as the circle C_(1) Statemnet I Radius of Circle C_(2)=sqrt2(sqrt2+1)(sqrt2+2) Statement II Centres of both circles always lie on the line y=x.

A circle C_(1), of radius 2 touches both x -axis and y -axis.Another circle C_(1) whose radius is greater than 2 touches circle and both the axes.Then the radius of circle is

A circle S of radius 'a' is the director circle of another circle S_(1),S_(1) is the director circle of circle S_(2) and so on.If the sum of the radii of all these circle is 2, then the value of 'a' is 2+sqrt(2)(b)2-(1)/(sqrt(2))2-sqrt(2)(d)2+(1)/(sqrt(2))

If a circle of radius 3 units is touching the lines sqrt3 y^2 - 4xy +sqrt3 x^2 = 0 in the first quadrant then length of chord of contact to this circle is :

The line 2x-y+1=0 is tangent to the circle at the point (2,5) and the center of the circle lies on x-2y=4. The radius of the circle is 3sqrt(5)(b)5sqrt(3)(c)2sqrt(5)(d)5sqrt(2)

Let C be a circle with two diameters intersecting at an angle of 30^(@). A circle S is tangent to both the diameters and to C and has radius unity.The largest radius of C is 1+sqrt(6)+sqrt(2)(b)1+sqrt(6)-sqrt(2)sqrt(6)+sqrt(2)-11 (d) none of these

Given b=2,c=sqrt(3),/_A=30^(0), then inradius of o+ABC is (sqrt(3)-1)/(2) (b) (sqrt(3)+1)/(2) (c) (sqrt(3)-1)/(4) (d) none of these
