how to solve 2nd queston?
ReplyDeleteLook if two circles touch externally, then the distance between their centres is equal to the sum of their radii.
ReplyDeleteBy using this property we can solve this question.
(distance is already given in question)
TRY IT OUT ONCE AGAIN AND DO REPLY..! ANSWER(The radii of the two circles is 11cm and 3cm)
