Let the radius of the bigger circle be X
and the radius of smaller inner circle be Y
Then, 2πX = 2 x 22/7 x X = 88
44X / 7 = 88
X = 88 x 7/ 44
X = 14 cm
2πY = 66
2 x 22/7 x Y = 66
44/7 x Y = 66
Y = 66 x 7/44
Y = 21/2 = 10.5 cm
Therefore, the width of the ring is X - Y
= 14 - 10.5 = 3.5 cm
I hope it helped.
