Question

$\huge \underbrace \mathfrak \red{hello࿐꧂}$
define cross section area​

Answer 1

The cross-sectional area is the area of a two-dimensional shape that is obtained when a three-dimensional object - such as a cylinder - is sliced perpendicular to some specified axis at a point. For example, the cross-section of a cylinder - when sliced parallel to its base - is a circle.

Answer 2

$\huge \underbrace \mathfrak \gray{ANSWER}$

In geometry and science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces. Cutting an object into slices creates many parallel cross-sections
