Question

A race track is in the form of ring whose inner circumference is 352 metre and the outer circumference is 396 metre. Find the width of the track

Answer 1

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

Answer 2

Answer:- Width of the track is 7 m and the area of track is 2618 sq.m
