Use the shell method to write and evaluate the de y = 8 - x -1 6- YA 2- x 4

Use the disk method to find the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis.y= 1 /sqrt1+x^2 , y=0, x=−1, x=1

The integral that represent the volume generated by rotation the area bounded by 9=7e -3x² 2 19=0,x=0,X=6 about the x-axis. find the area enclosed by the two line 2 x= a, x=2a, and the hyperbola xy=B²
