00:00:01.720 --> 00:00:06.580
The pie chart shows the results of a survey of how students travel to school.
00:00:07.320 --> 00:00:10.080
What is the most common method of travel?
00:00:11.860 --> 00:00:17.010
The most common answer in any pie chart will be denoted by the largest sector.
00:00:17.880 --> 00:00:24.010
This is because the areas of each sector are proportional to the quantities they represent.
00:00:24.840 --> 00:00:29.370
It is clear from the pie chart that the largest sector corresponds to taxi.
00:00:29.650 --> 00:00:33.140
Therefore, this is the most common method of travel to school.
00:00:34.570 --> 00:00:43.030
Whilst it is not required in this question, we can see from the pie chart that the sector for taxi corresponds to half of the circle.
00:00:44.240 --> 00:00:49.590
This means that one-half or 50 percent of the students travel to school by taxi.
00:00:50.870 --> 00:00:54.800
The metro sector corresponds to one-quarter of the circle.
00:00:55.580 --> 00:00:59.320
This is equal to 25 percent of the students.
00:01:00.050 --> 00:01:06.270
Whilst the actual values arenâ€™t given, it appears that the sector for bus and walking are equal.
00:01:06.640 --> 00:01:09.850
Therefore, they correspond to one-eighth of the circle.
00:01:10.820 --> 00:01:14.160
This is equal to 12.5 percent.
00:01:15.260 --> 00:01:25.180
We could also convert these percentages or fractions into the central angles as the angles in a circle add up to 360 degrees.
00:01:26.340 --> 00:01:36.690
The angle for taxi will be 180 degrees; for metro, 90 degrees; and for bus and walking, both 45 degrees.
00:01:37.980 --> 00:01:46.750
It is always worth checking at this point that our angles sum to 360 degrees and our percentages sum to 100.
