Pie chart question?

Suppose a garden plot contains 5 zinnias, 10 irises, 11 marigolds, 15 hollyhocks, and 23 lilies. If you


were to make a pie chart of the flowers in the plot, What would be the central angle for each?





(Example, 38 degrees-Hollyhocks, 76 degrees-Lilies and so on..)

Pie chart question?
The total number of flowers is





5 + 10 + 11 + 15 + 23 = 64





The angle at the centre which represents 1 flower is 360/64 =





5.625 degrees.





I hope you can take it from there...
Reply:You have:


5 zinnias,


10 irises,


11 marigolds,


15 hollyhocks, and


23 lilies.





The total number of flowers is 5+10 +11+15+23=64


The angle at the centre which represents 1 flower is 360/64 or 5.625 degrees


5 zinnias --%26gt; 5*360/64 or 5*5.625 degrees


10 irises --%26gt; 10*360/64 or 10*5.625 degrees


11 marigolds--%26gt; 11*360/64 or 11*5.625 degrees


15 hollyhocks--%26gt; 15*360/64 or 15*5.625 degrees


23 lilies --%26gt;23*360/64 or 23*5.625 degrees
