Width of the circular park = Outer radius - Inner radius
Now circumference of a circle = 2 pi r
Outer circumference = 264
2 × 22 / 7 × r = 264
44r / 7 = 264
44r = 264 × 7
44r = 1848
r = 1848 / 44 = 42
Inner Circumference = 220
2 × 22 / 7 × r = 220
44r / 7 = 220
44r = 220 × 7
44r = 1540
r = 1540 / 44 = 35
Width = 42 - 35 = 7
So width of the circular track is 7m
Hope it helps you.
