" he equation of four circies are "(x+a)^(2)+(u+a)^(2)=a^(2)" ,The radius of a circle touching ofl the four eircles is "

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

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

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 equation of four circles are (x+-a)^2+(y+-a)^2=a^2 . The radius of a circle touching all the four circles externally is

The equation of the four circles are (x pm a)^2 + (y pm a)^2 = a^2 . The radius of the smallest circle, which touches all the four circles, is:

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