Find the volume of the solid generated bounded by x = Jy – 4, x = y? – 8y+ 16, rotated about the Y - axis (use washer method)

For the sphers x-12+y+22+z-42=36 and x2+y2+z2=64, find the ratio of their a surface areas. b volumes.

A line intersects the xy plane at an x– intercept of N and a y intercept of F. Determine the volume of the solid formed by the line and coordinate axes if the axis of rotation is the x- axis.

Find the volume of the solid generated bounded by x = Jy-2, x = y? - 4y+ 4, rotated about the x- axis. (use washer method)
