Step-by-step explanation:

Outer Circumference = 132 m

=> Radius = Circumference / 2π

=> Radius = 132 / (2 × 22/7)

=> Radius = 132 / (44/7)

=> Radius = 132 × 7/44

=> Radius = 3 × 7

=> Radius = 21 m

Inner Circumference = 88 m

=> Radius = Circumference / 2π

=> Radius = 88 / (2 × 22/7)

=> Radius = 88 / (44/7)

=> Radius = 88 × 7/44

=> Radius = 2 × 7

=> Radius = 14 m

Width of the ring = Outer Radius - Inner radius

= 21 - 14

= 7 m
