Question

a race track is in the form of circle whose inner circumference is 396m and outer circumference is 440m. how can i find the width and area of the track?

Answer 1

Step-by-step explanation:

inner circumference = 396 m

outer circumference = 440m

width = (440-396)/(2*22/7)

= (44*7)/44

= 7m

radius of inner circle = 396/(2*22/7)

= 63m

radius of outer circle = 440/(2*22/7)

= 70 m

area of track = 22/7*(70^2-63^2)

=22/7*(931)

22*(133)

=2926 sq.m
