Question: A circular park has a path of uniform width around. The difference between outer and inner circumferences of the circular path is 132 m. Its width is $ ( take\pi =\frac{22}{7} ) $
Options:

Show Answer
Answer:
Correct Answer: C
Solution:
- Let $ r_1 $ and $ r_2 $ be the radius of inner and outer circle,
$ \therefore $ $ 2\pi r_2-2\pi r_1=132 $
$ \Rightarrow $ $ r_2-r_1=\frac{132\times 7}{2\times 22} $
$ \Rightarrow $ $ r_2-r_1=21m $
