What if the “slices” aren’t solid? • pigsflyguy.com/sitebuildercontent/sitebuilderfiles/sec_07_02_washer_method.ppt
Washers f(x) • Consider the area between two functions rotated about the axis • Now we have a hollow solid • We will sum the volumes of washers g(x) a b
Washers f(x) g(x) a b Outer Function Inner Function
The Method of Washers • Find the volume of the solid formed by revolving the region bounded by y = (x) and y = x² over the interval [0, 1] about the x – axis. glory.gc.maricopa.edu/~avolpe/230page/7.2calc2discsnadwashers.ppt
