HEXAGON
A hexagon is a
polygon with six sides. A polygon
is a closed plain figure bounded by three or more straight sides
that meet in pairs in the same number of vertices, that do not intersect
other than at these vertices.
Vertices is the plural of vertex. Vertex means
the point opposite the base of a figure or the point of intersection of
two sides of a plain figure or angle.
To find the area of a hexagon use
the formula A = ^{3}/_{2}
xr² x √3
Where A = area and r = radius.
The radius
is the straight line joining the centre of a circle or sphere to any point
on the circumference or surface. The length of this line is usually
denoted by the symbol r.
OCTAGON
An octagon is a polygon with eight sides.
A polygon is a closed plain figure bounded by three or more straight sides
that meet in pairs in the same number of vertices, that do not intersect
other than at these vertices.
Vertices is the plural of vertex. Vertex means the point opposite the base of a figure or the point of intersection of
two sides of a plain figure or angle.
To find the area of an octagon use
the formula A = 2 x
r² x
√2
Where A = area and r = radius.
The radius is the straight line joining the centre of a circle or sphere to any point
on the circumference or surface. The length of this line is usually
denoted by the symbol r.
CIRCLE
A circle is a closed plane curve where every
point is equally distant from the centre.
To find the area of a circle use
the formula A = p
xr²
Where A = area,
p= pi (3.14) and r = radius.
RADIUS
The radius
is the straight line joining the centre of a circle or sphere to any point
on the circumference or surface. The length of this line is usually
denoted by the symbol r.
