Homework Help Overview
The discussion revolves around determining the size of a farm based on the area devoted to vegetables, specifically 15 hectares, and its representation in a pie chart format with angles. Participants are exploring the relationship between the angle representing vegetables and the total area of the farm.
Discussion Character
- Exploratory, Assumption checking, Problem interpretation
Approaches and Questions Raised
- Participants are attempting to understand how to relate the angle of 30 degrees to the total area of the farm. There are questions about the correct method to calculate the fraction of the farm represented by vegetables and how to interpret the pie chart data.
Discussion Status
The discussion is ongoing, with various interpretations being explored. Some participants are questioning the initial calculations and assumptions, while others are attempting to clarify the relationship between the angles and the total farm size. Guidance has been offered regarding the need to convert angles into fractions or percentages of the whole farm area.
Contextual Notes
There appears to be confusion regarding the conversion of angles to area and the correct interpretation of the pie chart. Participants are also addressing terminology issues, such as the correct spelling of "hectares." The discussion is framed within the constraints of a homework assignment, which may limit the information available for solving the problem.
Correct me, if I'm wrong please.

No, you don't multiply the angle by the number of hectares (not hectors).Phisico said:
What fraction of the pie chart is devoted to vegetables?

your solution is not correct. First you need to figure out what what fraction of the whole farm is vegetables.

I multiplied 15* 12=180, which is the same as in the book

ok let's begin again...
you already know that full circle is 360°. The degrees for Hay, Vegetables and Wheat are given to you. Degrees for Grazing you should easily calculate, try it. Then try to convert all this info into fractions (or percentage if you prefer) of the whole farm area (represented here as the full circle). Once you have this calculated, it is easy to answer all the questions.

30° is 1/12 of the full circle, but I have no idea what you did to get 126.Phisico said:
Your later answer of 180 hectares for the whole farm is more reasonable.
So 30° of the pie chart corresponds to 15 hectares. Does he have more or less of the farm devoted to wheat?Phisico said:
