1. Let R be the region bounded by the graphs of y= sinx and y = 1 - sinx on (pi/6, 5pi/6)

Use the washer or disk method to set up (but do not evaluate) an integral that will determine the volume of the solid obtained by revolving R about the line y=3

2.Use calculus determine volume of the solid generated when R is revolved around the x-axis?

Let R be the region bounded by x=y^2 -4y + 4 and the vertical lines x=0 and x=1.
