Common cross‑section shapes (when slices are perpendicular to the axis):
Base: region bounded by (y = \sin x), (y = 0), (x=0), (x=\pi). Cross sections perpendicular to the x‑axis are semicircles (diameter in base). Find volume.
I can’t directly provide or attach a PDF file, but I can give you a , including practice problem ideas and where to find (or how to create) a high-quality PDF for practice. Quick Overview: Volume by Cross Sections For a solid perpendicular to the x‑axis , with cross‑sectional area (A(x)) from (x=a) to (x=b):
