(360) by 100% (total comparison, you can determine how many degrees of

the circle makeup 1 percent:

360 + 100% = 3.6 degrees in 1 percent.

At this point, you know that 3.6 degrees of the circle equals 1 percent,

and you know the percentage each segment represents.

With this

information, you can determine the number of degrees each segment uses by

multiplying each segment's percentage by 3.6 (the number degrees in 1%):

To plot the segments using a standard protractor (figure 1-32), place the

"0" graduation at the 12 o'clock position (this places the 180 graduation

at the 6 o'clock position).

The largest segment of the pie chart is

1170; therefore, it is the first segment you plot, moving clockwise from

the "0" percent graduation and marking that point on the circle.

Figure 1-32.

Standard protractor

The first (largest) segment of the pie chart ends at 117; therefore,

117 is the starting point of the next segment. The next segment you

must plot uses 90 of the pie chart. To find the ending point of this

segment you add the starting point of the
