22. find the area of the surface generated by revolving the
parametric curve about the y-axis.
x = 2 sin t + 1 , y = 2 cos t + 5 , (0) less than or equal to
(t) less than or equal to (pi/4)
Consider the region bounded by y = x2 −6x+9 and y = 9−3x. Set up, but do not evaluate, an integral to find the volume of the solid generated by revolving this region about the x-axis.
⃗ Find the volume of the solid of revolution obtained
by revolving the planeregion bounded by ? = ? − ?²
, ? = 0 about line ? = 2 .
