Question

You have been asked to produce a pie chart to record the results of a local election. The total amounts of votes received was 800. Calculate the number of degrees that each of the results would be represented by on the pie chart. Mr green 250 votes, Mrs grey 50 votes, Miss Purple 125 votes, Mr orange 375 votes

Answer 1

A pie chart is a circular chart that is divided into slices to represent numerical proportions. In a pie chart, each slice corresponds to a particular category. The size of each slice is proportional to the quantity it represents. The entire pie represents the total data set and each slice of the pie is a particular category within the whole.

The total degrees in a circle (and thus in a pie chart) are 360 degrees. The number of degrees that each candidate's results represents in the pie chart can be found by the following formula:

(Number of votes for the candidate / Total number of votes) * 360

Let's calculate the degrees for each candidate:

1. **Mr Green**: (250 / 800) * 360 = 112.5 degrees
2. **Mrs Grey**: (50 / 800) * 360 = 22.5 degrees
3. **Miss Purple**: (125 / 800) * 360 = 56.25 degrees
4. **Mr Orange**: (375 / 800) * 360 = 168.75 degrees

Therefore, in the pie chart, Mr Green would be represented by 112.5 degrees, Mrs Grey by 22.5 degrees, Miss Purple by 56.25 degrees, and Mr Orange by 168.75 degrees.
