A circle graph is being drawn as part of an analysis of tax disbursements in a certain state. One of the categories is “roads.” The total disbursement under consideration is $13,486,241.76. Of that amount $1,896,042.03 went to “roads.”What percent of the area of the circle graph should be included under this category? If the radius of the circle graph is to be 7, what is the area of the “roads” sector? How many degrees are in its central angle? B C
