Answer & Solution

Correct Answer

(C) \(\frac{3 \pi}{2}\)

Step-by-step Solution

Detailed explanation

\(4 y^{2}=x^{2}(4-x)(x-2)\) \(|y|=\frac{|x|}{2} \sqrt{(4-x)(x-2)}\) \(\Rightarrow y_{1}=\frac{x}{2} \sqrt{(4-x)(x-2)}\) and \(y_{2}=\frac{-x}{2} \sqrt{(4-x)(x-2)}\) \(D : x \in[2,4]\) Required Area…
