The following pie chart is created to show the total value of items stocked in a sports shop for 4 different sports.
Using the angle marked on the pie chart, and the fact that the shop stocks $12 000 worth of Golf items, find the total value of the shop’s stock across the 4 sports.
The angle marked on the diagram is 90°.
So a quarter of the stock is for Golf.
We can multiply this by 4 to find the total value of the shop’s stock.
Total value is $48 000
Given that the angle on the pie chart for Tennis is 72°, find the value of Tennis items the shop stocks.
The fraction of the value of the shop’s stock will be the same as the fraction of the circle for each category.
Therefore the value of tennis items will be
Value of tennis items is $9 600
