**Download Cross Section Area Of Circle Pictures**. Any theoretical plane placed through a sphere will result in a circle (think about this for a few moments). The cross section or the cross sectional area is the area of such a cut.

The area of the cross section is 15 square inches. Area of a circle= π r2 divide your value of cross sectional area by π square root this value and multiply it by 2 that value is diameter. Find the cross sectional area of a cylinder given the diameter with help from a longtime mathematics educator in this free video clip.

### Find the area of the following figures:

If a cross section is composed of a collection of basic shapes whose centroidal locations are known with respect to some reference point, then the note that the first moment of the area is used when calculating the centroid of a cross section with respect to some origin (as discussed previously). Circle is the shape with minimum radius of gyration, compared to any other section with the same area a. Given what i've just told you, i encourage you to pause the video and see if you can figure out the volume of this thing that i've shaded in a little bit. Area moment of inertia for typical cross sections ii.
