Grade seven learners recorded animals in the park as follows; 15 elephants, 25 gazelles, 30 giraffes,10 lions and 20 zebras. If they were re-presented the information on a pie chart, what angle will represent the number of zebras in the park?
To find the angle that will represent the number of zebras in the park on the pie chart, we first need to calculate the total number of animals in the park.
Total number of animals = 15 (elephants) + 25 (gazelles) + 30 (giraffes) + 10 (lions) + 20 (zebras)
Total number of animals = 100
Next, we need to find the proportion of zebras out of the total number of animals:
Proportion of zebras = Number of zebras / Total number of animals
Proportion of zebras = 20 / 100
Proportion of zebras = 0.2
Finally, we can calculate the angle that will represent the number of zebras on the pie chart:
Angle = Proportion of zebras * 360 degrees
Angle = 0.2 * 360
Angle = 72 degrees
Therefore, the angle that will represent the number of zebras in the park on the pie chart is 72 degrees.
