Question

A race track is in the form of a ring whose inner circumference is 352 and the outer circumference is 396 find the width of the track
​

Answer 1

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

Answer 2

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
