WebbIt is given that two circle having radii 3.5 cm and 4.8 cm touch each other internally. We know, the distance between the centres of the circles touching internally is equal to the difference of their radii. ∴ Distance between the centres of the two circles = 4.8 cm − 3.5 cm = 1.3 cm. Thus, the distance between their centres is 1.3 cm.
