A) \[\frac{100}{\pi }\] metre
B) \[\frac{250}{\pi }\] metre
C) \[\frac{500}{\pi }\] metre
D) \[\frac{600}{\pi }\] metre
Correct Answer: C
Solution :
\[AB=100\]metre \[\because \] \[{{360}^{o}}=2\pi r\] \[\therefore \] \[{{36}^{o}}=\frac{2\pi r}{360}\times 36=\frac{\pi r}{5}\] \[\therefore \] \[\frac{\pi r}{5}=100\,\,\,\Rightarrow \,\,\,r=\frac{500}{\pi }\] metreYou need to login to perform this action.
