2. The region R is bounded by the graphs of x + y = 4 , y = 2x + 3, and x = 5. Set up the integral for the volume of the solid generated if R is revolved about the line y = - 2 . Do not evaluate. 3. The region R is bounded by the x-axis and the graph of y = x2 -4. Set up the integral for the volume of the solid generated if R is revolved about the line x = 5. Do not evaluate
