we are now learning pie where is when you basically:

 * The distance around a cicle is called its circumference. The distance across a circle through its center is called its diameter. We use the Greek letter [[image:http://www.mathgoodies.com/lessons/vol2/images/pi.gif width="12" height="10" caption="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: [[image:http://www.mathgoodies.com/lessons/vol2/images/circum_formula.gif width="59" height="12" caption="C equals Pi times d"]]. For simplicity, we use [[image:http://www.mathgoodies.com/lessons/vol2/images/pi.gif width="12" height="10" caption="Pi"]] = 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: [[image:http://www.mathgoodies.com/lessons/vol2/images/diam_formula.gif width="54" height="13" caption="[IMAGE]"]]. || [[image:http://www.mathgoodies.com/lessons/vol2/images/tab.gif width="15" height="1" caption=" "]] ||


 * || 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 cm2, 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 area of this circle would be 28.26 cm2 However, it is easier to use one of the following formulas: ||

 * where [[image:http://www.mathgoodies.com/lessons/vol2/images/A.gif width="13" height="12" caption="A"]] is the area, and [[image:http://www.mathgoodies.com/lessons/vol2/images/r.gif width="9" height="11" caption="r"]] is the radius. Let's look at some examples involving the area of a circle. In each of the three examples below, we will use [[image:http://www.mathgoodies.com/lessons/vol2/images/pi.gif width="12" height="10" caption="Pi"]]= 3.14 in our calculations. ||
