Area refers to the surface area of a plane, cone, sphere, cuboid, cube, and many more two or three dimensional objects. However, the term 'Area of Cross' section refers to the area of a circular ring, such as that enclosing the mouth of a wire, or that of a tunnel, etc. It is essentially the curved opening that is referred to as cross sectional area.
