Question

radii of the two circle touching internally are 4.5 cm. and 2 cm. find the distance between their centers

Answer 1

my friend ,first let we understand some concepts

If the circle touch internally,
distance between the centres=R2-R1{where R1 and R2 are radius of the circles}


if the circle touch externally,
distance between the centres=R1+R2

therefore ,let we come to the answer,
by the first formula we get ,
distance between centres=4.5-2=2.5.

hope it helps

Answer 2

Answer:

2.5

Step-by-step explanation:

minus both the radii
