Answer & Solution

Correct Answer

(C) \(16\)

Step-by-step Solution

Detailed explanation

finding their intersection \(pts\) \(y^{2}=8 x\; and\; y^{2}=-16(x-3)\) \(8 x=-16 x+48\) \(24 x=48\) \(x=2 ; y=\pm 4\) Required Area \(=2 \cdot \int \limits_{0}^{4}({3-\frac{y^{2}}{16}}-{\frac{y^{2}}{8}}) d y\)…
