SOLVE ALL OF THEM!!

1. Sketch the grayhs ofx = 1,?2 23? and v = x. Shade the region bounded between the two etuves. Find the volume of the solid that is formed by revolving the region shaded about the x-axis. 2. Sketch the graphs of y = 5 + (I'll; x = 4 and y = 5. Shade the region bounded by the curves. Find the volume of the solid that is formed by revolving the region shaded about the \"jg-axis. 3. Sketch the grayhs of J: = [v - 2)? y = x + 4., and the y-axis. Shade the region bounded by the curves. Find the volume of the solid that is formed by revolving the region shaded about the iii-axis
