A) \[307{{m}^{2}}\]
B) \[308{{m}^{2}}\]
C) \[309{{m}^{2}}\]
D) not possible
Correct Answer: C
Solution :
The area of the circle having radius \[=\frac{1}{2}({{b}_{1}}+{{b}_{2}})h\] According to the question,\[=\pi {{r}^{2}}\] \[2\pi r\]Required area \[AOBC=\frac{\theta }{{{360}^{o}}}\pi {{r}^{2}}\]
