| Refer to Design A |
| The area of each sector of the brooch is |
A) \[44m{{m}^{2}}\]
B) \[52m{{m}^{2}}\]
C) \[77m{{m}^{2}}\]
D) \[68m{{m}^{2}}\]
Correct Answer: C
Solution :
Here, we see that total circle is divided into 8 parts. \[\therefore \]Area of each sector \[=\frac{1}{8}\times \]Area of circle \[=\frac{1}{8}\times \pi {{r}^{2}}\] \[=\frac{1}{8}\times \frac{22}{7}\times 14\times 14\] \[=77\,\,m{{m}^{2}}\]
