Question

two circles with radii 8.5cm and 2.5cm touch each other internally find distance between their centres ​

Answer 1

Given :- two circles with radii 8.5cm and 2.5cm which touches each other internally

We know,

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

So, distance between their centres = 8.5cm - 2.5cm = 6cm
