To complete the table, we need to calculate the number of degrees for each activity. The total number of hours in a day is 24, which corresponds to 360∘360^\circ in a pie chart. The formula to find the degrees for each activity is:

Degrees=(Number of hours for activityTotal number of hours)×360∘\text{Degrees} = \left( \frac{\text{Number of hours for activity}}{\text{Total number of hours}} \right) \times 360^\circ
  1. Calculate the degrees for each activity.

    • School: 524×360∘=5×15∘=75∘\frac{5}{24} \times 360^\circ = 5 \times 15^\circ = 75^\circ
    • Meals: 124×360∘=1×15∘=15∘\frac{1}{24} \times 360^\circ = 1 \times 15^\circ = 15^\circ
    • Home work: 324×360∘=3×15∘=45∘\frac{3}{24} \times 360^\circ = 3 \times 15^\circ = 45^\circ
    • TV: 224×360∘=2×15∘=30∘\frac{2}{24} \times 360^\circ = 2 \times 15^\circ = 30^\circ
    • Travel: 124×360∘=1×15∘=15∘\frac{1}{24} \times 360^\circ = 1 \times 15^\circ = 15^\circ
    • Sleep: 824×360∘=8×15∘=120∘\frac{8}{24} \times 360^\circ = 8 \times 15^\circ = 120^\circ
    • Other: 424×360∘=4×15∘=60∘\frac{4}{24} \times 360^\circ = 4 \times 15^\circ = 60^\circ
  2. Fill in the table with the calculated degrees.
