If `r_1a n dr_2` are the radii of the smallest and the largest circles, respectively, which pass though (5, 6) and touch the circle `(x-2)^2+y^2=4,` then `r_1r_2` is `4/(41)` (b) `(41)/4` `5/(41)` (d) `(41)/6`

If r_1a n dr_2 are the radii of the smallest and the largest circles, respectively, which pass though (5, 6) and touch the circle (x-2)^2+y^2=4, then r_1r_2 is (a) 4/(41) (b) (41)/4 (c) 5/(41) (d) (41)/6

If r_1a n dr_2 are the radii of the smallest and the largest circles, respectively, which pass though (5, 6) and touch the circle (x-2)^2+y^2=4, then r_1r_2 is (a) 4/(41) (b) (41)/4 (c) 5/(41) (d) (41)/6

If r_(1) and r_(2) are the radii of the smallest and the largest circles,respectively,which pass though (5,6) and touch the circle (x-2)^(2)+y^(2)=4, then r_(1)r_(2) is (4)/(41) (b) (41)/(4)(5)/(41) (d) (41)/(6)
