Answer:
See attachment.
Explanation:
A pie chart visually represents data in a circular format, where each slice corresponds to a proportion of the whole, providing a clear picture of how the data is distributed or composed in a dataset.
To construct a pie chart, first complete the given table.
Sum the frequencies:

Enter 36 in the total frequency box.
To calculate the fraction of each row, divide the frequency by the total frequency:





The fraction total is one.
In a circle, there are 360°. Therefore, to find the angle of each slice of the pie chart, multiply the fraction that each slice represents by 360°:





The total angle is 360°.
Therefore, the completed table is:

To construct the pie chart, draw a circle and divide it into sectors according to the given angles (see attachment).
