Question 1 Easy

Three slices of a pie chart have angles 110°, 100° and 60°. The rest of the pie is one more slice. What is its angle?

Show answer

Answer: 90°

  1. The angles in a pie chart add to 360°. The three known angles add to 110 + 100 + 60 = 270.
  2. 360 − 270 = 90.
  • Method (1): The angles in a pie chart add to 360°. The three known angles add to 110 + 100 + 60 = 270.
  • Accuracy (1): Answer 90°

Question 2 Easy

A pie chart shows the drinks chosen by 30 people. 9 of them chose tea. What is the angle for tea?

Show answer

Answer: 108°

  1. The full circle is 360° for 30 people, so each person is worth 360 ÷ 30 = 12°.
  2. 9 people × 12° = 108°.
  • Method (1): The full circle is 360° for 30 people, so each person is worth 360 ÷ 30 = 12°.
  • Accuracy (1): Answer 108°

Question 3 Medium

A pie chart shows the drinks chosen by 45 people. 3 of them chose tea. What is the angle for tea?

Show answer

Answer: 24°

  1. The full circle is 360° for 45 people, so each person is worth 360 ÷ 45 = 8°.
  2. 3 people × 8° = 24°.
  • Method (1): The full circle is 360° for 45 people, so each person is worth 360 ÷ 45 = 8°.
  • Accuracy (1): Answer 24°

Question 4 Medium

A pie chart shows 45 people. The angle for bus is 40°. How many people chose bus?

Show answer

Answer: 5

  1. Each person is worth 360 ÷ 45 = 8°.
  2. Number of people: 40 ÷ 8 = 5.
  • Method (1): Each person is worth 360 ÷ 45 = 8°.
  • Accuracy (1): Answer 5

Question 5 Hard

A pie chart shows 60 people. The angle for bus is 48°. How many people chose bus?

Show answer

Answer: 8

  1. Each person is worth 360 ÷ 60 = 6°.
  2. Number of people: 48 ÷ 6 = 8.
  • Method (1): Each person is worth 360 ÷ 60 = 6°.
  • Accuracy (1): Answer 8

Question 6 Hard

Three slices of a pie chart have angles 140°, 90° and 60°. The rest of the pie is one more slice. What is its angle?

Show answer

Answer: 70°

  1. The angles in a pie chart add to 360°. The three known angles add to 140 + 90 + 60 = 290.
  2. 360 − 290 = 70.
  • Method (1): The angles in a pie chart add to 360°. The three known angles add to 140 + 90 + 60 = 290.
  • Accuracy (1): Answer 70°
