# Two circles having radii 3.5 cm and 4.8 cm touch each other internally. Find the distance between their centres.

Answer :

Given: Two circles are touching each other internally.

∵The distance between the centres of the circles touching internally is equal to the difference of their radii.

⇒distance between their centres = 4.8 cm – 3.5 cm = 1.3 cm
