This method is often called the method of disks or the method of rings. Let’s do an example. Example 1 Determine the volume of the solid obtained by rotating the region bounded by y = x2 −4x+5 y = x 2 − 4 x + 5, x = 1 x = 1, x =

The Volume (V) of the solid is obtained by rotating the region x = f (y) when rotated about the y-axis on the interval of [a,b], then the volume is: V = ∫ a b 2 π y f ( y) d y Here the x
