A) \[\frac{(\angle A+\angle C)}{360{}^\circ }\times \pi \times {{(5.5)}^{2}}\]
B) \[\frac{(\angle B+\angle C)}{360{}^\circ }\times \pi \times {{(5.6)}^{2}}\]
C) \[\frac{(\angle A+\angle C)}{360{}^\circ }\times \pi \times {{(3.5)}^{2}}\]
D) \[\frac{(\angle B+\angle C)}{360{}^\circ }\times \pi \times {{(3.5)}^{2}}\]
Correct Answer: D
Solution :
| [d] Area of the region grazed by the buffalo and the horse |
| \[=\frac{\angle B}{360{}^\circ }\times \pi \times {{(3.5)}^{2}}+\frac{\angle C}{360{}^\circ }\times \pi ({{3.5}_{-2}}\] |
| \[=\frac{(\angle B+\angle C)}{360{}^\circ }\times {{(3.5)}^{2}}\] |
