We can work out the percentage for a given pie chart using the steps given below, To convert the data into degrees we use the formula: (Given Data ÷ Total value of Data) × 360°.To calculate the percentage of the given data, we use the formula: (Frequency ÷ Total Frequency) × 100.Based on these, there are two main formulas used in pie charts: Hence, the total of all the data is equal to 360°. It is also known that a circle subtends an angle of 360°. We know that the total value of the pie is always 100%. Hence, looking at the color divisions made in the pie chart we can conclude that: Quantity of Flour To calculate the exact amount of ingredients that are added to the cake, we divide the whole sector's value, i.e., 100 by the number of sectors. Solution: As we can see, the pie is divided into 10 slices or sectors. What would be the exact quantity of each of the ingredients represented in specific colors in the following pie chart? The various colors represent the ingredients used to prepare the cake. Let us look at the following example of the following pie chart that represents the ingredients used to prepare a butter cake.Įxample: The whole pie represents a value of 100. It is also used to compare the given data. Pie charts, also commonly known as pie diagrams help in interpreting and representing the data more clearly. Each of these sectors or slices represents the proportionate part of the whole. Pie Chart DefinitionĪ pie chart is a type of graph that records data in a circular manner that is further divided into sectors for representing the data of that particular part out of the whole part. The shape of a pie chart is circular where the pie represents the whole data and the slice out of the pie represents the parts of the data and records it discretely. It is one of the most commonly used graphs to represent data using the attributes of circles, spheres, and angular data to represent real-world information. A pie chart is a type of a chart that visually displays data in a circular graph.
