Step-by-step explanation:
Answer :
Distance between their centres is 25 cm or 5 cm .
Solution :
Let the radii of the circles be r1 and r2
r1=10cm and r2=15cm
By theorem of touching circles, the centres and point of contact are collinear . Here there can be two cases.
Case 1:
The circles touch each other externally
Distance between their centres =r1+r2
=10+15
=25cm
Case 2 :
The circle touch each other internally
Distance between their centres =r2−r1
=15−10
=5cm
i hope it will help u
