A circle S 1 of area 36 π cm 2 touches the coordinate axes. Another circle S 2 smaller than S 1 also touches the coordinate axes as well as S 1 also, then the radius of S 2 is -
A
2cm
B
cm
C
12 – 
cm
cm
D
18 – 
cm
cm
Text Solution
Verified by ExpertsThe correct answer is:
D
Let the radius of S 2 is r
r + r + 6 = 
6
r = 6 
= 6(3 – 
) = 18 –
