Washers!
Washers Consider the area between two functions rotated about the axis Now we have a hollow solid We will sum the volumes of washers f(x) a b g(x)
Washers f(x) a b g(x) 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
