Question

В классе 36 учеников. по математике за четверть отметку 5 имеют 8 человек, отметку 4 -12 человек а остальные отметку 3 построй круговую диаграмму

Answer 1

круговая диаграмма=3радусов
3/36=10 град- на одного человека
8*10=80 град- имеют 5
12*10=120 град- имеют 4
остальные 360-(80+120)=160град- имеют три 

Answer 2

Circle Diagram for Math Grades in a Class

To create a circle diagram representing the math grades in a class of 36 students, we need to consider the distribution of grades. According to the information provided, 8 students have a grade of 5, 12 students have a grade of 4, and the remaining students have a grade of 3.

To construct the circle diagram, we can divide it into three sections, each representing a different grade. The size of each section will be proportional to the number of students with that grade.

Here is a breakdown of the circle diagram:

- Grade 5: 8 students - Grade 4: 12 students - Grade 3: 36 - 8 - 12 = 16 students

To calculate the angle for each section, we can use the formula:

angle = (number of students with a grade / total number of students) * 360 degrees

Using this formula, we can calculate the angles for each grade:

- Grade 5: (8 / 36) * 360 = 80 degrees - Grade 4: (12 / 36) * 360 = 120 degrees - Grade 3: (16 / 36) * 360 = 160 degrees

Now, we can create the circle diagram:


In the diagram, the section for Grade 5 will have an angle of 80 degrees, the section for Grade 4 will have an angle of 120 degrees, and the section for Grade 3 will have an angle of 160 degrees.

Please note that the diagram is for illustrative purposes only and the actual appearance may vary based on the software or tool used to create it.
