Question

7. The inner circumference of a circular track is 242 m. The track is uniformly 7 m wide. Find the
area of the track.
​

Answer 1

Answer:

Circumference of the inner circle=2πr=24π =>r=12m

Radius of the outer circle =14m

Therefore, circumference of the outer circle =2π(14)

=2×22

=88m

(Assuming π=

7

22

)
