Question

Two circles of radii 5.5 CM and 3.3 CM touch each other internally. What is the distance between their centers? ​

Answer 1

Answer:

Two circles can touch each other internally or externally. ∴ Distance between centres = 5.5 + 3.3 or 5.5 – 3.3 = 8.8 or 2.2

Answer 2

Given r

1 =5.5 and r 2 =3.3

Distance between the centres of circles touching each other =r

1 +r2 =5.5+3.3=8.8cm
