Options
- A8 units
- B5 units
- C7 units
- DNone of these
Correct answer
B. 5 units
Step-by-step solution
Radius of smaller circle is r = 2 units (given) Since, it is touching both the axes, so its centre is ( 2 , 2 ) The distance between their centers = r + R = 5 - 2 2 + 6 - 2 2 = 3 2 + 4 2 = 25 = 5 u n i t s
