Geometric Shapes With Circular Cross Sections

Any two dimensional shape with one straight edge can be rotated about that edge to form a solid with circular cross sections.

Geometric shapes with circular cross sections. This is the currently selected item. Its projection is known as the cross section area. Volume by cross section.

It is called a prism because it is a 3 dimensional object. This sphere has a circle in the center crossing through the middle of the shape. This is in till it gets to the top which has a point at the tip.

It technology has a base of a circle and from the base grows more and more circle. Getting ready for solid geometry. Equivalently a symmetrical 2d figure can be rotated through 180 degrees about its mid axis to form a solid with full circle cross sections.

Slicing a rectangular pyramid. Cross section area and volume. The cross section of this object is a triangle.

This is a cross section of a piece of celery. When a plane cuts a solid object an area is projected onto the plane. The cross sections for different 3d shapes are given here.

Before that we are going to learn two important terminologies such as. Relate common 3d solids with their 2d cross sections taken parallel perpendicular and diagonal relative to the base. That plane is then perpendicular to the axis of symmetry.
