7 questions in the course bank use Circle graph, in Reading Graphs & Estimation.
Problem 1
Which graph best shows how temperature changes over a day?
- Bar graph
- Line graph
- Circle graph
Worked answer
Line graph
A line graph shows a quantity changing over time.
Problem 2
Which graph best shows how a budget splits into categories?
- Bar graph
- Line graph
- Circle graph
Worked answer
Circle graph
A circle graph shows parts of a whole, summing to 100%.
Problem 3
A circle graph shows 25% of 800 students walk to school. How many is that?
Worked answer
200
0.25 × 800 = 200
Problem 4
Which graph best compares the populations of five different towns?
- Bar graph
- Line graph
- Circle graph
Worked answer
Bar graph
A bar graph compares separate categories.
Problem 5
A circle graph of a $2,400 budget shows housing at 35% and food at 20%. How much more goes on housing?
Worked answer
360
35% - 20% = 15%
0.15 × 2400 = 360
Problem 6
A circle graph shows sections of 30%, 25%, 20% and 15%. What percent is the remaining section?
Worked answer
10
30 + 25 + 20 + 15 = 90
100 - 90 = 10%
Problem 7
The sections of a circle graph must add up to what percent?
Worked answer
100
A circle graph shows parts of a single whole, so the sections total 100%.
If they do not, the graph is wrong.
