Cracking The Ap Calculus ab Exam 2018

8.Use   the method  of  cylindrical shells  to  find    the volume  of  the solid   that    results when    the region

bounded by  y   =   2 , x   =   4,  and y   =   0   is  revolved    around  the y-axis.

9.Find  the volume  of  the solid   whose   base    is  the region  between the semi-circle y   =       and

the x-axis  and whose   cross-sections  perpendicular   to  the x-axis  are squares with    a   side    on  the base.

10.Find the volume of the solid whose base is the region between y = x^2 and y = 4 and whose
perpendicular cross-sections are isosceles right triangles with the hypotenuse on the base.
