SUMMARY
The discussion focuses on calculating the volume of revolution for the area R bounded by the curves \(y^2 + x^2 = 5\), \(y = 2x\), and the y-axis (x = 0) in the first quadrant. The user proposes using the cylindrical shell method and presents the integral \( \int_0^1 x(\sqrt{5 - x^2} - 2x) \cdot 2\pi \, dx \) to find the volume T when R is rotated around the Y-axis. The integral formulation is confirmed as correct for this specific problem.
