A geometric figure with a polygonal base and triangular sides is called a pyramid.
A paraboloid.
This figure is a CONE.
A pyramid is any three-dimensional polyhedron where the faces other than the base are triangular and converge at one point, called the apex. The formula for finding the volume of a pyramid is . There are some tutorials at the related link below that can help you figure out how to use this formula.
Such a figure is a pyramid.
A geometric figure with a polygonal base and triangular sides is called a pyramid.
A paraboloid.
The shape in question is called a square pyramid.
A cone is a figure that contains 2 faces and 1 corner. The faces are the base and that slanted surface wrapped around the base. The corner is the apex of the slanted surface.
One possibility is a heptagonal pyramid - with a heptagon as a base and seven triangular faces meeting at the apex.
cone; circle is the base
This figure is a CONE.
The height of a triangle is the perpendicular distance measured from the chosen base (or base extension*) to its opposite vertex (or apex)+.* If any of the shorter sides of an obtuse triangle is chosen to be the base, an extension need to be drawn to this base so that a perpendicular can be constructed from the apex down to this base extension.There are three sides to a triangle, hence three possible bases. Each base will have a corresponding height that is measured from the opposite vertex or apex+.A vertex is the point when 2 sides of a figure intersect.(Read more: vertex)+ A triangle has 3 vertices. 2 vertices defines the length of the base. There remains one vertex that is not touching the base. This vertex is opposite to the base (or base extension) and it is referred to as the apex.
