Materials Needed : 1) Thin wooden sticks 10" x 1/2" 2) Protractors 3) Papers 4) Pencils Recommended Strategy : 1) Give each student three sticks, a protractor, a paper and a pencil. Let each student put the paper on his or her desk. Then take one of the sticks and put it on the paper horizontally. Take a second stick and join it to the first stick vertically at the left endpoint. The two sticks join together to form a pattern. The two sticks represent two rays having the same endpoint. The stick put horizon Read More Go to Site Area of a Circle Votes:0 Area of a Circle Unit 2 The distance around a circle is called its circumference . The distance across a circle through its center is called its diameter . We use the Greek letter (pronounced Pi ) to represent the ratio of the circumference of a circle to the diameter. In the last lesson, we learned that the formula for circumference of a circle is: . For simplicity, we use = 3.14. We know from the last lesson that the diameter of a circle is twice as long as the radius . This relationship is expressed in the following formula: . The area of a circle is the number of square units inside that circle. If each square in the circle to the left has an area of 1 cm 2 , you could count the total number of squares to get the area of this circle. Thus, if there were a total of 28.26 squares, the ar Read More Go to Site Circles - Diameter, Circumference, Radius and the Discovery of Pi Votes:0 Circles - Diameter, Circumference, Radius and the Discovery of Pi Circles - Diameter, Circumference, Radius and the Discovery of Pi Kathleen Ryan Randolph Magnet School 10409 S.

Circle ? set of all points in a plane that are the same distance from a given point (equidistant). The given point is called the center P. Chord ? segment whose endpoints are on the circle. Diameter ? a chord that passes through the center of the circle. all diameters are congruent. Radius ? segment that has the center as one endpoint and a point on the circle as the other endpoint. all radii are congruent.
