What Pie? (What Would You Use: Part 3) Pie Charts http://nces.ed.gov/nceskids/graphing/bar_pie_chart.asp?temp=5899734 1. What group is 17.2% of the total? 2. Hispanic students represent what percent of the total? 3. Which group makes up the largest sector of the pie? 4. How many American Indian/Alaskan students are represented by the 1.2% http://pulse.pharmacy.arizona.edu/math/what_pie.html Make a pie chart to represent the following data: Color of Cars Red Blue White Black Number of Cars 60 15 30 15 1. What is the total number of cars? 2. Write the fraction of the total number of cars that are the following color: a. Red b. Blue c. White d. Black 3. Using the fact that there are 360 in a whole circle and that 120 cars also represent the whole circle for our data, calculate the central angle of the sector that represents the cars of the following colors: a. Red b. Blue c. White d. Black http://pulse.pharmacy.arizona.edu/math/what_pie.html 4. Using a compass, draw a circle in the space provided and a line segment from the center of the circle to another point on the circle. 5. Using a protractor, draw a line segment to make the appropriate angle for the sector representing the red cars. Continue making the appropriate angles for the sectors representing the other car colors as you move around the circle. Remember to make a table telling what each sector represents. http://pulse.pharmacy.arizona.edu/math/what_pie.html Calculating how much is in each sector: The pie chart below shows the ingredients used to make a sausage and mushroom pizza. The fraction of each ingredient by weight is shown in the pie chart below. Note that the sum of the decimal sizes of each slice is equal to 1 or the "whole" pizza. http://www.mathleague.com/help/data/data.htm#piecharts Given we know the pizza weighs a total of 1.6 kg, how do you calculate how much each of the ingredients weigh?
