A) \[22\,\,m\]
B) \[56\,\,m\]
C) \[45\,\,m\]
D) \[35\,\,m\]
Correct Answer: D
Solution :
Length of arc \[=2\pi r\times \frac{\theta }{{{360}^{o}}}\] \[\Rightarrow \] \[44=2\times \frac{22}{7}\times r\times \frac{72}{360}\] \[\Rightarrow \] \[r=\frac{44\times 7\times 5}{44}=35m\] Which is the length of the rope.You need to login to perform this action.
