distance b/t the center of circle-1=4.5(radios)
" of circle 2=2cm( " )
therefore the distance b/t their centers=4.5-2 (mentioned-touching internally)
=2.5cm
" of circle 2=2cm( " )

Let R and r are the Radii of two
circles.
R = 4.8 cm,
r = 3.5 cm
Distance between two centres
= R - r
= 4.8 cm - 3.5 cm
= 1.3 cm
