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
