The total number of students who attended the exam is 375.
So, if we graph the given data on a pie chart, then 375 students are denoted by 360 degrees. So, 1 student is denoted by 360/375 = 0.96 degrees.
The students who failed are 44. So,
![44*0.96=42.24\text{ degrees}](https://img.qammunity.org/2023/formulas/mathematics/college/fzs9mvd9fn252775nsplkm74ne97xx1qxs.png)
Thus, 42 degrees would be used to indicate the F region on a pie chart.
