	Conic Sections: Circles (Site not responding. Last check: 2007-10-10)
		Definition: A circle is all points equidistant (the distance is called the radius) from one point (which is called the center of the circle).
		Since the equation of a circle is written by using the distance formula from (x, y) to the center and setting this equal to the radius, we are now ready to build a standard formula for a circle.
		In addition to the graph generated by the graphing calculator, a graph produced by EXCEL is also presented.

	Review of Circle Graphs (Site not responding. Last check: 2007-10-10)
		Circle graphs, also called pie charts, are a type of graph used to represent a part to whole relationship.
		From the circle graph we know this is 45:10, which is 4.5:1.
		When we are presented with a circle graph, we want to be able to make statements about the sectors of the graph, relative to one another, and relative to the entire circle.

	Talk:Cycle graph - Wikipedia, the free encyclopedia
		A circle graph is a circle with n equidistant points.
		It is also useful for teaching children about repeating end digits in multiplication: a circle graph with 10 vertices, with the multiples of three graphed in sequence, results in [0,3,6,9,2,5,8,1,4,7,0], with the sequence infinitely repeating.
		In group theory, a "cycle graph" is a graph showing the structure of cycles in a group.

		Heterosexuality is shown as a summer circle and homosexuality as a winter circle.
		In a sexually free society, the bi circle would be the largest because that is the natural sexuality of 80% of the population.
		In the world of today and the near future, however, the bi circle is smaller than the straight circle (due to the bi-phobia of the straight majority) and yet, larger than the gay circle (due to bisexuality being more widespread than 100% homosexuality).

		Tell students this is called a circle graph, although it is also called a pie graph or pie chart (for the obvious reason that it resembles a pie cut into pieces).
		However, individual numbers-number of servings, which is important for this particular information-cannot be determined from the circle graph from the graphical representation; they must be stated through labeling.
		Note that students will need to use a compass (to draw circles and mark their centers) and a protractor (to measure in degrees and mark off sections on circles) in Part B #3.

	Circle Graphs (Site not responding. Last check: 2007-10-10)
		To read a circle graph you must remember that the entire circle represents 100% of something.
		Then, using the degrees in Step 3, divide the circle into sectors ("slices of pie") by drawing a line from the center to the outer edge of the circle.
		Example: 25% of a circle is 25% of 360 degrees.

	NASA's KSNN™ - What’s a graph?
		Bar graphs show frequencies and help make comparisons to show “how much of something.” The trait used to sort the data on a bar graph is indicated on the horizontal axis.
		The entire circle represents all data and the total is divided into parts to represent groups within the data.
		The strength of a circle graph is that it clearly shows how the parts relate to the whole.

	Making a circle graph of a sample budget
		After tracing around the plate, find the center of the circle by folding the plate in half and creasing, then folding the plate in half again at a different place and creasing.
		Matching the circumference of the plate to the circle on the poster board, transfer a sharp pencil point hole through the plate to the poster board for the circle center.) Have each learner measure out the angle for their category on a piece of colored construction paper to fit on the 8-inch circle.
		This lesson could be followed up with an assignment for each of the learners to make circle graphs of their own personal budgets.
