4.6 Interpreting Circle Graphs

Focus: interpret circle graphs to solve problems.

Circle graphs allow information to be presented in a picture that can be easily interpreted
In a circle graph, each sector represents part of the whole.
The whole circle represents 100%
Every circle graph should have a title
Each sector should have a label and percentage
If the sector is small, it can be labelled off of the graph
A legend can be used in place of labels, but percentages should still be included
If we want to calculate how much of the whole a sector makes up, we multiply the total by the percent of the sector.

Eg. if 18% of a budget is spent on bills and the total spent is $2500, we take 18% of 2500 or 0.18 x 2500

b) Samson gets a raise of $500 per month. How will this affect his food budget?

a) Which type of program is watched for the greatest amount of time?

b) Which two types of programs are watched for approximately the same amount of time?

c) Estimate the fraction of time spent watching sitcoms.

d) Suppose TV is watched for 1000 days. Estimate how much time is spent watching sitcoms.

Land use system 
The Seigneurial System was restored rather than the Township System.

Focus: Develop and use a formula to find the area of a Triangle.

Can you find the differences between the triangles?

Formula for Area of a Triangle

If a triangle and parallelogram have the same base and height, the triangle will have half the area.
