### Create Circle Graphs

Construct a Circle
-compass, string

Create Central Angle
-central angle is formed by 2 radii, the vertex of the angle is at the center

Example

They got 360 in a circle because there is 365 days in a years but 365 is to hard to work.

25% like strawberry
25% like vanilla
50% like chocolate

Make a circle graph for the following info. 3 kids use the computer 1-3 days a week. 9 kids use the computer 0 days a week. 18 kinds use computer 4 or more days a week

Step 1 find how many total

3 + 9 + 18 = 30

Step 2 convert to percent

3/30 = 1/10 = 10/100 10% 1-3 days

9/30 = 3/10 = 30/100 30% 0 days

18/30 = 6/10 = 60/100 60% 4 or more

Step 3 convert % to degrees

10% of 306* = 36*

30% of 360* = 108*

60% of 360 +216*
