Question

a race track is in the form of a ring whose inner circumference is 264m and the outer circumference is 308m. find the width of a track ​

Answer 1

Step-by-step explanation:

Let the radius of inner track =r

2πr=352

2×22×r/7=352

r=56m

let the radius of outer track =R

2πR=396

2×22×R/7=396

R=63m

width of track= radius of outer track−radius of inner track

=63−56=7m.
