What is Cross Sectional Area?  Definition from ...
A cross sectional area is the area of the sliced portion of a 3D object, such as a pipe. When a pipe is sliced perpendicular to its longest axis, the cross sectional area will be calculated for the top part of the sliced portion, which is a circle. Calculating a crosssectional area is an integral part of trenchless rehabilitation methods ...
