Accreditation is a process in which school standards are evaluated by an accreditation agency. In the United States, this process is not completed by the federal government, but by states or private companies with varying rules and standards. Different groups promote accreditation for homeschoolers.
The circle is the simplest and best known conic section. As a conic section, the circle is the intersection of a plane perpendicular to the cone's axis. The geometric definition of a circle is the locus of all points a constant distance r {\displaystyle r} from a point ( h , k ) {\displaystyle (h,k)} and forming the circumference (C).
Note: that when the number of sides of a polygon is increased without limit, the sides merge into one line and polygon becomes a circle. Parts of a Circle : The radius of the circle is a straight line drawn from the center to the boundary line or the circumference.The plural of the word radius is radii. The diameter is the line crossing the circle and passing through the center.It is the twice of the length of the radius.The circumference of a circle is the boundary line or the perimeter of the circle. The chord is a straight line joining two points on the circumference points of a circle.The diameter is a special kind of the chord passing through the center. An arc is a part of the circumference between two points or a continuous piece of a circle. The shorter arc between and is called the minor arc.ote: that when the number of sides of a polygon is increased without limit, the sides merge into one line and polygon becomes a circle.
