Consider rotating "R" about the x-axis to form a solid of revolution. When we integrate to find the volume of revolution, using a washer method, what will be the volume of a typical slice (a single washer)? On (25 - (² + 1)²). Ar O [(x² + 1)²-5]. Ax Ο π(4 - x2)*. Δε Ο π(x2 + 1)*. Δε

Please show me the correct answer with clear and neat handwriting. I got 83349pi/512 as a wrong answer.

The region formed by y = 2x - x² and the x axis is revolved around the y-axis. Find the volume. (Shells are probably most helpful for this problem.)
