A) 8
B) 9
C) 10
D) 12
Correct Answer: D
Solution :
From the first radical sign \[{{x}^{2}}+{{y}^{2}}\le 16\]i.e. interior of a circle with circle (0, 0) and radius 4. From the 2nd radical sign \[y\le \,\,|x|\] i.e.,\[\frac{\text{3}}{\text{4}}\text{th}\] of the circle \[\therefore \]Required area \[=(\pi ,\,\,16)\frac{3}{4}=12\pi \]You need to login to perform this action.
