How is the number of vertices for a pyramid related to the name of the pyramid?
Subtract 1 from the number of vertices. Find the name of the polygon with that many sides. The pyramid has that polygon as its base. So, for example, 7 vertices. Subtract one and that gives 6. A six sided polygon is a hexagon. So the shape is a hexagon based (or hexagonal) pyramid.
How do you find the area of a polygon with only the radius given?
a polygon doesn't have a radius... a circle has a radius. the area of a circle is pi times the radius squared. * * * * * While it is true that a polygon does not have a radius, it does have a circumradius. This is the radius of the circle which passes through each of the polygon's vertices. If the circumradius is r units, and the polygon has n sides, then its area will be 1/2*n*r2*sin(2π/n) square units, where the angle is measured in radians.
How do you get the of a center of a regular polygon?
If it is a polygon with an even number (>2) of vertices, join any two pairs of opposite vertices. These lines will meet in the centre. If it is a polygon with an odd number (>1) of vertices, join any two vertices to the midpoints of the opposite sides. These lines will meet in the centre.
How do you find the area of the regular polygon if only the radius is given?
The circumradius is the radius of the circle which passes through each of the polygon's vertices. If the circumradius is r units, and the polygon has n sides, then its area will be Area = 1/2*n*r2*sin(2Ï€/n) square units, where the angle is measured in radians. If, instead, the radius of the inscribed circle (the apothem) is known to be x units, then Area = nx2*tan(Ï€/n)
How many vertices the pyramid have?
In geometry a pyramid is a generic term describing a shape that consists of a base that is a n-sided polygon, and n triangular faces attached to each of the polygon's sides which meet at an apex above the base. A pyramid with an n-sided polygon as base has n+1 faces, n+1 vertices and 2n edges.
What vertices of a polygon are located at 2-1 6-1 5-4 and 1-4 what is the area of the polygon?
+/- the square root of 3
How many vertices does a heart shape have?
No vertices (0). a heart shape is not a polygon shape, only polygon shapes have vertices.

How many faces and vertices in decagon?
A decagon is a 10 sided polygon that has 10 vertices and 1 flat face

Do prisms and pyramids have the same number of vertices?
Sometimes. A prism whose base is a n-sided polygon has the same number of vertices (2n) as a pyramid with a base that is a (2n-1)-sided polygon. For example, a triangular prism has the same number of vertices as a pentagonal pyramid.
How many vertices have a pyramid?
A pyramid, whose base is a polygon with n sides, has n+1 vertices. Thus a triangular pyramid (tetrahedron) has 4 vertices, a quadrilateral (square or rectangular) pyramid has 5 vertices; etc.
How many face edges and vertices has a square?
Vertices are the corners of the polygon so there are 4 in this instance and there are also 4 edges to a square which defines the 1 face.
How many vertices the pyramid have?

How many faces edges and vertices does a pentagon have?
A pentagon is a two dimensional polygon. As such it has no faces, because a face is a flat surface and two dimensional objects have no surface. It does have five edges and five vertices.
