Question

A region is bounded by the parabola 2x^2+4x+y=02x2+4x+y=0    and the line    y+2x+4=0y+2x+4=0.               

a] Evaluate the volume of the solid generated when the area of the region is revolved about  the line  x=1x=1.  (Use a single integral.)

b] Set up the integral  for the volume generated when the same area is revolved about the line y=−6y=−6. (Use a single integral.)
