A) \[56\text{ }m\]
B) \[\text{74 }m\]
C) \[\text{110 }m\]
D) \[\text{88 }m\]
Correct Answer: D
Solution :
(d):\[C=2\pi r\] \[\therefore \,C-r=r(2\pi -1)=74\Rightarrow r=\frac{74}{2\pi -1}\] \[\therefore 2\pi r=\frac{74\times 2\pi }{2\pi -1}\,\,\,\,=74\times \frac{44/7}{\frac{44}{7}-1}=74\times \frac{44}{37}=88\,cm\]You need to login to perform this action.
