# What is a circle graph

## Online Tutoring Is The Easiest, Most Cost-Effective Way For Students To Get The Help They Need Whenever They Need It.

A circle graph is a graph of a circle whose chords, when drawn from one point on the circle to another point on the circle intersect each other within the circle. Circle graphs are also known as pie graphs or pie charts, and the intersection of the chords in the circle is used to represent different proportions or statistical data of certain information. Circle graphs or pie charts are very useful and helpful in organizing information and to compare and represent ratio of a part with respect to the whole.

Example 1: In a basket of fruits there are 2 apples, 4 oranges and 2 peaches. Show the percentage of the fruits in a circle/pie graph.

Total number of fruits in the basket = 8

Number of apples= 2==> % of apples = 2/8 * 100% = 25%

Number of oranges= 4==> % of oranges = 4/8 * 100% = 50%

Students in dance club= 1==>% of them= 1/10 * 100% = 10%

Number of apples= 2==> % of apples = 2/8 * 100% = 25%

Number of oranges= 4==> % of oranges = 4/8 * 100% = 50%

Number of peaches= 2==> % of peaches = 2/8 * 100% = 25% Therefore the percent of each fruit is shown in the circle graph.

Example 2: In a class of 10 students, 4 students are in science club, 5 students are in sports club and 1 student is in dance club. Show the percentage of students in each club in a circle/pie graph.

Total number of students in the class= 10

Students in science club= 4==>% of them= 4/10 * 100% = 40%

Students in sports club= 5==>% of them= 5/10 * 100% = 50%

Students in dance club= 1==>% of them= 1/10 * 100% = 10% Therefore the percentage of students in each club is shown.
