Terra Nova Practice Lesson 23 Circle Graphs

Problem 1 ► Suppose you are constructing a circle graph. ► How many degrees represent the whole? ► A 90  ► B 100  ► C 180  ► D 360 

Problem 2 ► Suppose you are constructing a circle graph. ► What central angle represents 35% ► A 35  ► B 70  ► C 126  ► D 135 

Problem 3 ► Suppose you are constructing a circle graph. ► If the central angle measures 90 , then what percent of the whole does the central angle represent? ► A 10%C 45% ► B 25%D 90%

For questions 4 – 6, use the circle graph. It compares the ways students go to school

Problem 4 ► What percent of the students go to school by bus? ► A 13% ► B 40% ► C 45% ► D 80%

Problem 5 ► What is the measure of the central angle representing students who take a bus to school? ► A 144  ► B 140  ► C 80  ► D 40 

Problem 6 ► What is the measure of the central angle representing students who walk to school? ► A 150  ► B 162  ► C 170  ► D 182 

Answers ► 1 D ► 2 C ► 3 B ► 4 B ► 5 A ► 6 B
