Step-by-step explanation:
to get the width we need to find the radius of outer circle and inner circle
circumference of outer circle = 2πr = 616
2 × 22/7 × r = 616
r = 616 × 7/22 × 1/2
r = 28 × 7 × 1/2
r = 14 × 7
r = 98 m
radius of outer circular track = 98m
circumference of inner circular track = 2πr = 528
2 × 22/7 × r = 528
r = 528 × 7/22 × 1/2
r = 24 × 7 × 1/2
r = 12 × 7
r = 84 m
radius of inner circular track = 84 m
width of track = outer radius - inner radius
= 98 - 84
= 14 m
therefore width of track is = 14 m
hope you get your answer
