hello frnd!!
once again...
here's ur answer....
circumference of the first circle=121m
2πr=121m
2×22/7×r=121m
44/7×r=121m
r=121/1×7/44
r=847/44
r=19.25cm
circumference of second circle=154cm
2πr=154cm
2×22/7×r=154cm
44/7×r=154cm
r=154/1×7/44
r=1078/44
r=24.5cm
difference between their radius=24.5-19.25
=5.25cm
hope it helps
