Question

Draw a pie chart showing the following information. The table shows the colours preferred by a group of people.
 

Colours	Number of people
Blue	18
Green	9
Red	6
Yellow	3
Total	36

Answer 1

Here, central angle = \(360°\) and total number of people = \(36\)
 

Colours	Number of people	In fraction	Central angle
Blue	18	\(\frac{18}{36}\)	\(\frac{18}{36}\times 360\degree=180\degree\)
Green	9	\(\frac{9}{36}\)	\(\frac{9}{36}\times 360\degree=90\degree\)
Red	6	\(\frac{6}{36}\)	\(\frac{6}{36}\times 360\degree=60\degree\)
Yellow	3	\(\frac{3}{36}\)	\(\frac{3}{36}\times 360\degree=30\degree\)
