Answer:
The difference between the outer circle and the inner circle (R-r) = 7 cm.
The circumference of outer circle is given as 132 cm.
Finding the radius of the outer circle,
2πR = 132
R = 21 cm
Now circumference of inner circle is given as 88 cm.
Finding the radius of inner circle,
2πr = 88
r = 14 cm
Now we have to find the difference between the radii
(R-r) = (21-14) = 7 cm
