[ V = \int_c^d A(y) , dy ]

| Shape | Area formula | |-------|---------------| | Square (side = (s)) | (A = s^2) | | Equilateral triangle (side = (s)) | (A = \frac\sqrt34 s^2) | | Right isosceles triangle (leg = (s)) | (A = \frac12 s^2) | | Semicircle (diameter = (s)) | (A = \frac\pi8 s^2) | | Rectangle (height = (h), base = (s)) | (A = h \cdot s) |

Here, (s) is typically the length of the cross‑section at a given (x) or (y), found as the difference between two bounding curves. Problem: The base of a solid is the region bounded by (y = \sqrtx), (y = 0), and (x = 4). Cross‑sections perpendicular to the x‑axis are squares whose bases lie in the base region. Find the volume. volume by cross section practice problems pdf

Common cross‑section shapes (when slices are perpendicular to the axis):

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): [ V = \int_c^d A(y) , dy ]

For cross sections :

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. Find the volume

Base: circle (x^2 + y^2 = 9). Cross sections perpendicular to the x‑axis are equilateral triangles. Find volume.

Base: region between (y = 1) and (y = \cos x) from (x=-\pi/2) to (\pi/2). Cross sections perpendicular to the x‑axis are rectangles of height 3. Find volume.
