A) \[2\pi {{r}^{2}}\]
B) \[\pi {{r}^{2}}\]
C) \[\frac{\pi {{r}^{2}}}{2}\]
D) None of these
Correct Answer: C
Solution :
| [c] Required area \[=\frac{(\angle A+\angle B+\angle C)}{360{}^\circ }\times \pi {{r}^{2}}\] |
| \[=\frac{180{}^\circ }{360{}^\circ }\times \pi {{r}^{2}}=\frac{\pi {{r}^{2}}}{2}\] |
