Question

in a survey 40% people like tea 35% like coffee and the rest like milk find the central angle of the persons who liked t to draw a pie chart​

Answer 1

144° will be the central angle for tea

Answer 2

Answer: Tea- 144° , Coffee-126° and Milk- 90°

Step-by-step explanation:

Percentage who liked tea= 40%

Percentage who liked coffee= 35%

Percentage who liked milk= 100-(40+35)

= 25%

Central angle of the entire survey( total number of people involved) = 360°

Therefore, 100% corresponds to 360° ( 100% refers to the entire population involved in the survey)

So, 40% corresponds to = (360/100)*40=144°

Therefore, central angle for the persons who liked tea is 144°.

In the same way, coffee corresponds to 126° and milk corresponds to 90°.
