Question
A circular racing track has been developed in a field.
If the difference between the outer circumference and the inner circumference of the racing track is 33 m, then find the width of the track (in m). (Use Ο = 22/7)Solution
Let the Width of the track =rβ β rβ. 
Difference between the outer circumference and the inner circumference=33m. 2Οr Β β 2Ο rβ = 33m 2Ο(rβ β rβ) = 33 (rβ β rβ) =21/4 =5(1/4).
