Explanation Definition: Circle Graphs Another type of commonly used graph is the circle graph, also known as a pie chart. This graph is particularly useful in illustrating how a whole quantity is divided into parts—for example, income or expenses in a budget. Given data set is Tuition $1, 388, 000 Development $90, 000 Fund-raising $119,000 Athletic Dept. $44,000 Interest $75,000 Tax subsidy $29,000 TOTAL $1,745, 000 Construction of Circle graph To create a circle graph, first express the number in each category as a percentage of the total. Then convert this percentage to an angle in a circle. Remember that a circle is divided into sectors, so we multiply the percent by 360 to find the number of degrees for each category or sector. You can use a protractor to construct a circle graph. The first step in constructing a circle graph is to write the ratio of each entry to the total of the entries, as a percent. This is done by finding the total ( $ 1 , 745 , 000 ) and then dividing each entry by that total: Tuition: Tuition = income from Tuition Total income Tuition = 1388000 1745000 ⋅ 100 Tuition = 1388000 1745000 ⋅ 100 Tuition = 79.54 Tuition ≃ 79 % Development: Development = income from Development Total income Development = 90000 1745000 × 100 Development = 9000 1745 Development = 5.16 Development ≃ 5 % Fund-raising: Fund-raising = income from Fund-raising Total income Fund-raising = 119000 1745000 ×100 Fund-raising = 11900 1745 Fund-raising = 6
