What is a pie chart and how do you create one?

• A pie chart is a line graph that shows trends over time.

• A pie chart is a table that lists data values in rows and columns.

• A pie chart is a circular graphic divided into slices representing data proportions.

• A pie chart is a bar graph used to compare different categories.

Given the data: A: 30, B: 50, C: 20, create a pie chart.

• A pie chart with slices representing A: 50%, B: 30%, C: 20%.

• A pie chart with slices representing A: 30%, B: 50%, C: 20%.

• A pie chart with equal slices for A, B, and C.

• A pie chart with slices representing A: 20%, B: 30%, C: 50%.

Interpret the following bar graph: Sales in 2022 for A, B, C.

• Sales for all products were equal in 2022.

• Product C had the highest sales, followed by A, with B having the lowest sales.

• Product B had the highest sales, followed by A, with C having the lowest sales.

• Product A had the highest sales, followed by B, with C having the lowest sales.
