How many degrees represent the whole data set in a pie chart?
Show answer
360°. A complete circle contains 360 degrees.
If 1/3 of the data is represented in a pie chart, what is the angle of that sector?
Show answer
120°. Calculate: 1/3 × 360° = 120°.
If a sector in a pie chart represents 10% of the data, what is the angle of that sector?
Show answer
36°. Calculate: 10% × 360° = 0.10 × 360° = 36°.
If a sector in a pie chart has an angle of 72°, what fraction of the total does it represent in simplest form?
Show answer
1/5. Calculate: 72°/360° = 1/5.
If 29 out of 40 people gave a particular response, what is the angle for that sector in a pie chart?
Show answer
261°. Calculate: (29/40) × 360° = 261°.
What is the formula to convert a frequency to an angle in a pie chart?
Show answer
Angle = (frequency ÷ total) × 360°.
If 2/5 of 240 members are senior runners, how many degrees represent senior runners in a pie chart?
Show answer
144°. Calculate: 2/5 × 360° = 144°.
If 15% of cupcakes are strawberry, what is the angle for the strawberry sector in a pie chart?
Show answer
54°. Calculate: 15% × 360° = 0.15 × 360° = 54°.
What three pieces of equipment are essential for accurately drawing a pie chart?
Show answer
Protractor (to measure angles), compass or circle template (to draw the circle), and ruler (to draw radii).
