A) \[1018.5\text{ }{{m}^{2}}\]
B) \[12.25\text{ }{{m}^{2}}\]
C) \[38.5\text{ }{{m}^{2}}\]
D) \[\text{40 }{{m}^{2}}\]
Correct Answer: C
Solution :
(c): \[C=2\pi r=22\Rightarrow r=\frac{7}{2}\] \[A=\pi {{r}^{2}}=\pi \times {{\left( \frac{7}{2} \right)}^{2}}=38.5\]You need to login to perform this action.
