Answer:
5
Step-by-step explanation:
given; R 1=8,R 2=4
circumference of first circle=2*22/7*8
=352/7
circumference of second circle=2*22/7*4
=132/7
difference between circumference of both first and second circle
=352/7-132/7
=220/7
radius of the circle with circumference 220/7:
220/7=2*22/7*R 3
R 3=220/44
R 3=5
