Question

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

Answer 1

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
