Question

28% of deaths on city roads may be attributed to drunken driving. The number of degrees needed to represent this as a slice of a pie chart is
A. 120
B. 100
C. 180
D. 212

Accepted Answer

The degrees needed to represent drunken driving deaths in the pie chart is approximately 100 degrees. A pie chart represents a complete circle of 360 degrees. Each percentage of the whole corresponds to a proportional arc of the circle. To find the degrees for a given percentage, multiply the percentage by 360 and divide by 100. For 28%, this gives 100.8 degrees, which rounds to 100.
