Cylinder: A cylinder is another three-dimensional shape, but instead of having a pointed top like a cone, it has two parallel circular bases connected by curved sides.
Frustum: A frustum is what you get when you slice off the top portion of a cone or pyramid parallel to its base. It resembles a truncated version of the original shape.
Sphere:A sphere is a perfectly round three-dimensional object where all points on its surface are equidistant from its center. Think of it as resembling a basketball or planet Earth.
