A) \[2121.74\,c{{m}^{2}}\]
B) \[2011.14\,c{{m}^{2}}\]
C) \[200.4\,c{{m}^{2}}\]
D) \[1904.44\,c{{m}^{2}}\]
Correct Answer: A
Solution :
Required Area \[=\pi {{(30)}^{2}}-\pi {{(15)}^{2}}\] \[\pi [(30+15)(30-15)]\,=\frac{22}{7}\,\times 675\,c{{m}^{2}}\] \[=2121.74\,c{{m}^{2}}\]You need to login to perform this action.
