Verified Solution

Answer & Solution

Correct Answer

(A) \(2(\pi-2)\) sq units

Step-by-step Solution

Detailed explanation

Radius: \(r = \sqrt{8} = 2\sqrt{2}\) Angle of sector: \(\alpha = \arccos\left(\frac{2}{2\sqrt{2}}\right) = \frac{\pi}{4}\). Total angle \(2\alpha = \frac{\pi}{2}\). Area of sector: \(A_{sector} = \frac{1}{2}r^2 (2\alpha) = \frac{1}{2}(8)\left(\frac{\pi}{2}\right) = 2\pi\).…
