12 out of 30 people chose blue as their favourite colour, calculate the angle you would use for blue on a pie chart

One way:

(12)/(30) x 360 (360 degrees in a circle which is what a pie chart is)
or
(2)/(5) x 360
which is
(2)/(5)x (360)/(1) = 144⁰ angle

Answer:

The angle you would use for blue on a pie chart is 144°.

Explanation:

Consider the provided information.

The full chart would have 360 Degrees. That means 30 people equals to 360°


30\ people=360

Divide both sides by 30.


1\ people=12

Now multiply both sides by 12.


1* 12\ people=12* 12


12\ people=144

Hence, the angle you would use for blue on a pie chart is 144°.
