A circle?
A circle is one example of a plane figure that is not a polygon. A V is also not a polygon.
A polyhedron is a three-dimensional figure formed by flat surfaces that are bounded by polygons joining along their sides (the faces of the polyhedron).A circle is not a polygon, but we can say that a circle is the limit of a regular polygon with n sides. It means that if n becomes larger and larger, the polygon shape approaches to a circle. A circle is a two dimensional figure as a polygon is, but a three dimensional figure whose base(s) is/are a circle cannot be called a polyhedron.
You can divide the diameter by two.
Assuming you are talking about a circle:* If you know the radius of the circle, multiply that by 2. * If you know the circumference of the circle, divide that by pi. * If you know nothing, you need to measure either the radius, the diameter, or the circumference.

A circle?
yes a circle is closed but is not a polygon
A circle is one example of a plane figure that is not a polygon. A V is also not a polygon.
Circle
If the circle is five feet across - that is the diameter.
A sphere as a polygon is a shape with three or more sides and a sphere has no sides
A polyhedron is a three-dimensional figure formed by flat surfaces that are bounded by polygons joining along their sides (the faces of the polyhedron).A circle is not a polygon, but we can say that a circle is the limit of a regular polygon with n sides. It means that if n becomes larger and larger, the polygon shape approaches to a circle. A circle is a two dimensional figure as a polygon is, but a three dimensional figure whose base(s) is/are a circle cannot be called a polyhedron.
Any closed figure formed by a set of straight linesegments is a polygon. If the segments are curved such as in a circle or oval, the closed figure is not a polygon.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
