Chapter 49: Problem 2

Create a pie chart. Display the following information in the form of a pie chart. Typical composition of a breakfast cereal. $$ \begin{array}{ll} \hline \text { Content } & \text { Typical value per } \mathbf{1 0 0} \mathbf{~ g} \\ \hline \text { Protein } & 6 \mathrm{~g} \\ \text { Carbohydrate } & 83 \mathrm{~g} \\ \text { Fat } & 5 \mathrm{~g} \\ \text { Fibre } & 4 \mathrm{~g} \\ \text { Other } & 2 \mathrm{~g} \\ \hline \end{array} $$

Short Answer

Expert verified
Every component has a percentage calculated based on its proportion to the total 100g content using the formula: (component weight / total weight) * 100. This percentage is depicted in the pie chart where each segment represents a different component of the cereal composition: protein (6%), carbohydrate (83%), fat (5%), fibre (4%), and other (2%).

Step by step solution

01

Determine the total value

Since these components make up the entire cereal content, add up all the mentioned quantities to determine the total value. This will be: 6g (protein) + 83g (carbohydrate) + 5g (fat) + 4g (fibre) + 2g (other) = 100g.
02

Determine the percentage of each component

Next, determine the percentage each component contributes to the total composition. The percentage value is calculated by taking the individual component value, dividing by the total (100g), and then multiplying by 100. For example, for protein, it would be: (6g / 100g) * 100 = 6%.
03

Create the pie chart

Plot the pie chart using the percentage values for each component. This is usually done by setting each percentage as a proportional section of the pie, where the entire pie represents 100%. Each segment's size reflects the component's contribution to the total cereal content.
04

Label the pie chart

Label each section of pie chart with its corresponding component and percentage. This will give the viewer a complete understanding of the composition of the breakfast cereal.
