  • Session 9, Part C: Cross Sections - Annenberg Learner

    A cross section is the face you get when you make one slice through an object. Below is a sample slice through a cube, showing one of the cross sections you can get. The polygon formed by the slice is the cross section. The cross section cannot contain any piece of the original face; it all comes ...

  • Borehole Geometry Probe - Robertson Geologging

    The borehole-geometry probe consists of a four-arm caliper combined with a verticality measurement. The probe can replace the standard three-arm caliper with advantage where the borehole cross-section departs from circular and where directional information is required for well-completion studies and formation stress analysis.

  • How do you calculate the cross section area of a sphere?

    If I am correctly understanding the question. You are simply looking for the area of a circle or pi * R^2 or pi/4 * D^2. ----- The formula above is correct for the planar cross section area through the center of the sphere, where the constant pi = 3.14159.... and R is the radius of the sphere, and D is the diameter.
