A) 70
B) 35
C) 17.5
D) 140
Correct Answer: B
Solution :
Let radius of wheel = r cm According to the given condition, \[=2\pi rh=11\,\,\text{km}\] \[\Rightarrow \] \[2\times \frac{22}{7}\times r\times 5000=11\times 1000\times 100\] \[\Rightarrow \] \[r=\frac{7\times 11\times 1000\times 100}{2\times 22\times 5000}=35\,\,\text{cm}\]You need to login to perform this action.
