<p>Page 453 in the Blue Book</p>
<p>It shows a graph of car sales. The total amount of cars sold is 180. 30 cars were sold in April.</p>
<p>If the car sales data from these 6 months were illustrated by circle graph, what would be the measure of the central angle of the sector that represents the month of April?</p>
<p>a. 30 degrees
b. 54 degrees
c. 60 deg.
d. 108 deg.
e 120 deg.</p>
<p>I have a feeling I'm doing something really stupid...</p>
<p>Thanks :)</p>
