SOLVE ALL OF THEM!

4. Sketch the graphs of y = X2 4x + 5 and y = x + 1. Shade the region bounded between the two curves. Find the volume of the solid that is formed by revolving the region shaded about the yaxis. 5. Sketch the graphs of y = cos x, y = 0 and X = 0 from x = 0 to x = 130. Shade the region bounded by the curves. Find the volume of the solid that is formed by revolving the region shaded about the y-axis
