A) \[464\,\,c{{m}^{2}}\]
B) \[2464\,\,c{{m}^{2}}\]
C) \[4462\,\,{{m}^{2}}\]
D) None of these
Correct Answer: B
Solution :
Given here, the length of string = 28 m Now, the area of the cow can graze around must be a circular area whose radius is equal to the length of string = 28 m Thus, area of the circle \[=\pi {{r}^{2}}=\frac{22}{7}\times 28\times 28\] \[=2464\,\,{{\text{m}}^{2}}\]
