  1. Two circles touch each other internally. The radius of the larger circle is 6 cm and the distance between the centre is 2 cm, then the radius (in cms) of the other circle is
    1. 8
    2. 2
    3. 4
    4. 3
Correct Option: C

As per the given in question , we draw a figure of two circles touch each other internally ,

The radius of the larger circle ( r1 ) = 6 cm
and the distance between the centre ( OO' ) = 2 cm
As we know that , OO' = r1 + r2
Radius of other circle = 6 – 2 = 4 cm.
