A class was asked to represent daily milk delivery data on a pie chart. Describe the steps involved in creating this pie chart.

Guide learners to sum the milk delivered each day to find the total.

Explain that a full circle is $360^\circ$. For each day, calculate the fraction of the total milk it represents and multiply by $360^\circ$ to find the sector angle.

• Monday: $\frac{20}{120} \times 360^\circ = 60^\circ$
• Tuesday: $\frac{18}{120} \times 360^\circ = 54^\circ$
• Wednesday: $\frac{21}{120} \times 360^\circ = 63^\circ$
• Thursday: $\frac{15}{120} \times 360^\circ = 45^\circ$
• Friday: $\frac{24}{120} \times 360^\circ = 72^\circ$
• Saturday: $\frac{22}{120} \times 360^\circ = 66^\circ$

Instruct learners to draw a circle using a compass. Then, using a protractor, measure and draw each calculated angle from the center of the circle, creating sectors for each day.

Have learners label each sector with the corresponding day and its amount or percentage. Finally, give the pie chart a clear title, such as "Milk Delivered to Dairy in 6 Days."
