Algebra.Com's Answer #238634 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! You will need a compass to draw the circle. The \n" ); document.write( "compass automatically gives you the center of \n" ); document.write( "the circle. It is where the point of the compass \n" ); document.write( "sticks into the paper. Once you have drawn a circle, \n" ); document.write( "you will need a protractor that has angles marked \n" ); document.write( "off on it. It looks like a half circle with 0 degrees \n" ); document.write( "to 180 degrees marked off in 1 degree units. \n" ); document.write( " Now you need to look at the data that you want to \n" ); document.write( "put into a pie chart. Only certain kinds of data \n" ); document.write( "can be arranged into a pie chart. All the separate data \n" ); document.write( "items have to add up to 100% of something. \n" ); document.write( " An example is a person's budget of spending and saving \n" ); document.write( "from monthly income. \n" ); document.write( "For example: \n" ); document.write( "food: $300/month \n" ); document.write( "rent: $1000/month \n" ); document.write( "entertainment: $150/month \n" ); document.write( "savings: $50/month \n" ); document.write( "If this adds up to monthly income, then it's 100% of income \n" ); document.write( "and can be put into a pie chart. \n" ); document.write( "The way to do this is to turn the data into pie slices with this \n" ); document.write( "formulas: \n" ); document.write( "(food amount)/(total budget) x 360 degrees \n" ); document.write( "(rent amount)/(total budget) x 360 degrees \n" ); document.write( "(entertainment)/(total budget) x 360 degrees \n" ); document.write( "(savings)/(total budget) x 360 degrees \n" ); document.write( "---------------------------------- \n" ); document.write( "What is the total budget? \n" ); document.write( "300 + 1000 + 150 + 50 = 1500 \n" ); document.write( "so, \n" ); document.write( "food: 300/1500 x 360 = 72 degrees \n" ); document.write( "rent: 1000/1500 x 360 = 240 degrees \n" ); document.write( "entertainment: 150/1500 x 360 = 36 degrees \n" ); document.write( "savings: 50/150 x 360 = 12 degrees \n" ); document.write( "----------------------------------- \n" ); document.write( "These are the pie slices and they should add up to a full pie, \n" ); document.write( "or 360 degrees: \n" ); document.write( "72 + 240 + 36 + 12 = 360 degrees \n" ); document.write( "Now draw a straight line from the center of the circle to \n" ); document.write( "the outer edge. Use the protractor to create 72 degrees \n" ); document.write( "from this line and draw the line at 72 degrees. \n" ); document.write( "Now go around the circle, marking off 240, 36, and 12 \n" ); document.write( "degrees to make up a full circle. Label the pie slices \n" ); document.write( "72 degrees: food \n" ); document.write( "240 degrees: rent \n" ); document.write( "and so on \n" ); document.write( " |
