A) \[254\,{{m}^{2}}\]
B) \[308\,{{m}^{2}}\]
C) \[245\,{{m}^{2}}\]
D) \[380\,{{m}^{2}}\]
Correct Answer: B
Solution :
The area that cow can graze is in the form of semicircle. Radius of semicircle Length of rope\[=14m\] Required area \[=\frac{1}{2}\times \pi {{r}^{2}}\] \[=\frac{1}{2}\times \frac{22}{7}\times 14\times 14=308\,{{m}^{2}}\]You need to login to perform this action.
