if two circle touch extenally then distance between center of circle is sum of its radius .
hence,
distance between center=15/2+25/2
=20 cm
if both circle touch internally then
distance between center=R-r=25/2-15/2
=5 cm
hence,
distance between center=15/2+25/2
=20 cm
if both circle touch internally then
distance between center=R-r=25/2-15/2
=5 cm
