A) \[88\text{ }c{{m}^{2}}\]
B) \[154\text{ }c{{m}^{2}}\]
C) \[616\,c{{m}^{2}}\]
D) \[1250\text{ }c{{m}^{2}}\]
Correct Answer: C
Solution :
| [c] Circumference of the circle = Perimeter of the rectangle \[=2\,(18+26)=88\,cm\] \[2\times \frac{22}{7}\times R=88\] \[\Rightarrow\] \[R=\left( 88\times \frac{7}{44} \right)=14\,cm\] Area of the circle \[=\pi {{R}^{2}}=\left( \frac{22}{7}\times 14\times 14 \right)=616\,c{{m}^{2}}\] |
