Question

A track in the form of a ring whose inner circumference is 132meter and outter circumference is 176meter. Find the width of the track.


please find and give​

Answer 1

Step-by-step explanation:

Let inner radius=r1

and outer radius =r2

Inner circumference=132m

2×π×r1=132

2×22/7×r1=132

r1=132×7/44

r1=21m

Outer circumference=176m

2×π×r2=176

r2=176×7/44

r2=28m

width of track =r2-r1

=7m
