A facet.
A side of a solid figure is called a face.
It is called a face.
The flat side of a three dimensional solid is called the face. The total area of all of the faces is called the surface area.
If its 2d its called a semi-circle, if its 3d its called a semi-sphere.
A flat surface of a solid is usually the face of the solid. +++ Also sometimes called a "facet", particularly on solids having very many flat faces.
The face of a triangle is the flat surface of the solid figure. _________________________________________________ A face is a side of a 3 dimensional figure. So, the number of faces a triangle would be 0.
a face.
In mathematics, a face is a flat surface that is a constituent of a three-dimensional geometric object, such as a polyhedron or a solid. Faces are typically polygons, such as triangles, rectangles, or pentagons, and they help define the shape and structure of the object. For example, a cube has six faces, each being a square.
If you are a solid figure with no vertices or edges, then you are a Sphere.From the lighter side: And that means that we can no longer be friends...
A frustum of a cone.Correct answer is: CYLINDER* * * * *A cylinder is like a special case. If the curved side of a frustum is perpendicular to the flat face, it makes a cylinder but why assume it is perpendicular? The figure could well be a frustum.
