Question

If two circles with radii 8 and 3 respectively touch internally, then find the distance between their centres.

Answer 1

Distance between centre = 8-3=5cm

Answer 2

Answer:

5

Step-by-step explanation:If the circles are touching internally, then

Radii of circle 1 ( R1 ) =8

Radii of circle 2 ( R2 )=3

Distance between its centers= R1-R2

i.e                                              = 8-3

                                                  =5
