Vedclass · Answer

(A) The curve $x = \sqrt{2 - y^2}$ represents the right half of the circle $x^2 + y^2 = 2$,which has a radius $r = \sqrt{2}$.The curves $|x| = |y|$ represent the lines $y = x$ and $y = -x$.These lines intersect the circle at points where $x^2 + x^2 = 2$,which gives $2x^2 = 2$,so $x^2 = 1$,meaning $x = 1$ (since $x \ge 0$).At $x = 1$,$y = 1$ and $y = -1$. The angle subtended by the arc at the center is from $	heta = -45^\circ$ to $	heta = 45^\circ$,which is $90^\circ$ or $\frac{\pi}{2}$ radians.The area of a circular sector is given by $\frac{1}{2} r^2 	heta$.Substituting $r^2 = 2$ and $	heta = \frac{\pi}{2}$,we get Area $= \frac{1}{2} 	imes 2 	imes \frac{\pi}{2} = \frac{\pi}{2}$.
