- Calculate the total number of items: 52 + 112 + 86 + 68 + 30 = 348.
- Find the percentage for each type: (Number of items / Total) × 100.
- Amethysts: (52 / 348) × 100 ≈ 14.94%.
- Ruby: (112 / 348) × 100 ≈ 32.18%.
- Diamond: (86 / 348) × 100 ≈ 24.71%.
- Sapphire: (68 / 348) × 100 ≈ 19.54%.
- Emerald: (30 / 348) × 100 ≈ 8.62%.
- Convert each percentage to degrees for the pie chart: (Percentage / 100) × 360°.
- Amethysts: (14.94 / 100) × 360° ≈ 53.8°.
- Ruby: (32.18 / 100) × 360° ≈ 115.8°.
- Diamond: (24.71 / 100) × 360° ≈ 88.9°.
- Sapphire: (19.54 / 100) × 360° ≈ 70.3°.
- Emerald: (8.62 / 100) × 360° ≈ 31.0°.
- Draw a circle and use a protractor to mark each sector with its corresponding degree measure, starting from a fixed point (e.g., 12 o’clock position) and proceeding clockwise or counterclockwise.
- Label each sector with the gemstone type and its percentage or count.
