What is the total number of cars?
2.
Write the fraction of the total number of cars that are the following color:
a. Red

Using the fact that there are 360 in a whole circle and that 120 cars also represent
the whole circle for our data, calculate the central angle of the sector that represents
the cars of the following colors:
a. Red
b. Blue
c.
White
d. Black

4. Using a compass, draw a circle in the space provided and a line segment from the center
of the circle to another point on the circle.
5. Using a protractor, draw a line segment to make the appropriate angle for the sector
representing the red cars. Continue making the appropriate angles for the sectors
representing the other car colors as you move around the circle. Remember to make a
table telling what each sector represents.

Calculating how much is in each sector:
The pie chart below shows the ingredients used to make a sausage and mushroom pizza. The
fraction of each ingredient by weight is shown in the pie chart below. Note that the sum of the
decimal sizes of each slice is equal to 1 or the "whole" pizza.

the ingredients weigh?
