Question

the inner circumference of a circular track is 200m and the outer circumference is 220m find the width of the track

Answer 1

let R be the outer radius & r be inner radius of the track
outer circumference = 2 pi R. inner circumference 2pi r=200
or, r=31.8m
and 2piR=220
or, R=35m

the width=35-31.8=3.21m
