Find the central angle for each student for constructing a pie chart if
No. of students = 10
Total no. of hours T.V watched = 25.5
no. of hours T.V watched by student 1 = 0.5 hours
no. of hours T.V watched by student 2 = 4 hours
no. of hours T.V watched by student 3 = 3 hours
no. of hours T.V watched by student 4 = 3.5 hours
no. of hours T.V watched by student 5 = 1.5 hours
no. of hours T.V watched by student 6 = 3.5 hours
no. of hours T.V watched by student 7 = 2 hours
no. of hours T.V watched by student 8 = 2 hours
no. of hours T.V watched by student 9 = 3.5 hours
no. of hours T.V watched by student 10 = 2 hours

central angle for student1 = 0.5/25.5 * 360 = 7.06 degrees
2nd student = 56.48 degrees
3rd student = 42.36 degrees
4th        =  49.42 deg
5th            = 21.18 deg
6th =                  49.42 deg
7th                =  28.24 deg
8th  =  28.24 deg
