Question

what type of graph is used to show a whole that is divided into parts?
bar graph
circle or pie graph.
line graph.
double line graph.

Explanation:

A circle or pie graph (pie chart) is used to represent a whole divided into parts, where each part's proportion is shown as a slice of the circle. Bar graphs compare quantities, line graphs show trends over time, and double line graphs compare two trends. So the graph for a whole divided into parts is a circle or pie graph.

Answer:

C. Circle or pie graph.
