Answer:
![\frac{1}{2} {r}^{2} ( \frac{1}{2}\pi - 1)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%7Br%7D%5E%7B2%7D%20%28%20%5Cfrac%7B1%7D%7B2%7D%5Cpi%20-%201%29)
option D is the right option.
solution,
Area of shaded region:
Area of sector-Area of ∆
![= \frac{90}{360} \times \pi {r}^{2} - \frac{1}{2} \times r \times r \\ = \frac{1}{4} \pi {r}^{2} - \frac{1}{2} {r}^{2} \\ = \frac{1}{2} {r}^{2} ( \frac{1}{2} \pi - 1)](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B90%7D%7B360%7D%20%20%5Ctimes%20%5Cpi%20%7Br%7D%5E%7B2%7D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20r%20%5Ctimes%20r%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%7D%7B4%7D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%7Br%7D%5E%7B2%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%7Br%7D%5E%7B2%7D%20%28%20%5Cfrac%7B1%7D%7B2%7D%20%5Cpi%20-%201%29)
