WebAnswer: We’re rotating around the x-axis, so washers would be vertical and cylindrical shells would be horizontal. There’s clearly a problem with using cylindrical shells, as their heights would be given by the distance from the curve to itself, which is tricky to get a handle on. Instead, let’s use washers. WebWhat is Washer Method? This process is a logical extension of the disk method for determining the volumes of the solids of revolution.
