What you'll learn

Identify the cross-section produced by horizontal, vertical, and diagonal cuts through rectangular prisms, cylinders, cones, pyramids, and spheres
Define a cross-section as the 2D shape formed when a plane cuts through a 3D solid
Recognize how changing the angle or position of the cutting plane changes the resulting cross-section
Identify which 3D solid results from rotating a given 2D shape around a specified axis, and state its radius and height from the shape's dimensions and the axis
