Question

A racetrack is in the form of ring whose inner circumference is 528meter and the outer circumference is 616meter. Find the width of the track.

Answer 1

inner circumference = 2πr
528 =2πr
after solving we get the value of r
r=84m
inner radius =84m
now
outer circumference= 616m
2πr=616
after solving we get the value of r
r=98m
outer radius =98m
width of track= outer radius-- inner radius
= 98-84
=14m answer

Answer 2
