Question

Need help for an assignment please and thank you.

In a college, there are 800 students in the first year, 950 students in the second year and 1000 students in the third year. If this data were graphed as a pie chart, what would be the size of the angle in the third year?

Answer 1

Answer:
`130.9^(\circ)`

Explanation:

Given

The number of students in the first year is 800

The number of students in the second year is 950

The number of students in the third year is 1000

If this data is graphed on a pie chart, then the area percentage of area occupied by third years is

`\Rightarrow (1000)/(1000+950+800)* 100=36.36\%`

Now, the angle around the center of the circle is
`360^(\circ)`

`\therefore \text{angle covered by third years=}0.3636* 360^(\circ)\\\Rightarrow 130.896\approx 130.9^(\circ)`
