Step-by-step explanation:
let the radius of inner track = r
2 pie r = 352
r = 56
let the radius of outer track = R
2 pie R = 396
R = 63
width of track = radius of outer track - radius of inner track
=63 - 56
= 7 m
hope it is helpful

To find the width of track, first we need to find the radius of both circles
inner circumference=352m
2πr=352m
= 2×22/7×r=352m
= 44/7×r=352m
= r=352/1×7/44
= r=56m
outer circumference=396m
2πr=396m
= 2×22/7×r=396m
= 44/7×r=396m
= r=396/1×7/44
= r=63
width of track = 63-56
= 7
