The region bounded by y=1/(x^3), y=0, x=4, x=10 is rotated about the line x=3.
What is the volume of the resulting solid?

The region bounded by y =5/x, y = 0, x = 4, and x = 6 is rotated about the x-axis. Find the volume of the resulting solid. Volume=

The region bounded by the given curves is rotated about the specified axis. Find the volume of the resulting solid by any method. y = -x2 + 6x - 8, y = 0; about the y -axis y = -x2 + 6x - 8, y = 0; about the x - axis y2 - x2 = 1, y = 2; about the x-axis y2 - x2 = 1,y = 2; about the y-axis
