Find the area of the circle:
Area = 3.14 x 12^2 = 3.24x144 = 452.16 cm^2
The sector is 60 degrees.
Multiply the area of the circle by the fraction of the sector:
452.16 x 60/360 = 75.36 cm^2

Step-by-step explanation:
In statistics, Bias can be described as a term which depicts error if a sample is not taken evenly or it depicts errors taken from an unjust sampling.
In statistics, sampling bias means the errors which occur if one part of the population is favoured more then the rest of the populations. In this kind of bias, the individuals for experimentation are not chosen randomly.
As the customer satisfaction survey was distributed in only one of the gates hence, it does not give a generalized result and the result is biased.
