Question

Find the width of a circular track with outer circumference 264m and inner circumference 220m

Answer 1

The answer is posted above

Answer 2

Width of circular track is 7 m.

Step-by-step explanation:

1. Let outer radius of circular track = R

  Outer circumference =264 m

  2×π×R =264     ...1)

2. Let inner radius of circular track = r

  Inner circumference =220 m

  2×π×r =264     ...2)

3. Subtracting equation 2) from equation 1)

 2×π×R- 2×π×r =264-220

 2×π(R-r)= 44

 $2\times \frac{22}{7}\times (R-r)=44$    ..3)

4. On solving equation 3), We get

Width of circular track ( R-r) =7 m
