1. The problem statement, all variables and given/known data Use the shell method to find the volume of the solid obtained by rotating the region bounded by y=x2, y=0 and x=1 about the x-axis. 2. Relevant equations lim Ʃ2∏RhΔw Δw->0 3. The attempt at a solution I realize this is hard to visualize without a graph. I uploaded how I split the graph. Solved for y and found y=0, 1. lim Ʃ2∏RhΔw Δw->0 =lim Ʃ2∏y(1-y)Δy // made it 1-y because y=x2. Δy->0 =lim Ʃ2∏(y-y2)Δy Δy->0 =2∏∫y-y2dy from 0->1 =2∏[y2/2-y3/3] from 0->1 =∏/3 Using Fundamental Theorem of Calculus, volume was found to be ∏/3. However this answer is incorrect. The answer is suppose to be ∏/5. I solved the question initially using the washer method and obtained the answer of ∏/5 but this question asks specifically to use shell method. I don't know how I can fix what I did wrong in this question. I assume I set the wrong h value. I also always get confused on what variable to use x or y, when taking into about if the rotation is about the x or y axis. Any help would be great thanks!
