Question

What angle would you use to represent 40 red
cars out of 90 cars in total on a pie chart?
a) 40 degrees
b) 90 degrees
c) 4 degrees
d) 160 degrees​

Answer 1

Answer:

160 degrees

Step-by-step explanation:

40/90 x 360 = 160

Answer 2

Given:

number of red cars$=40$

Total number of cars$=90$

To find: the angle of the red cars in a pie chart.

Solution:

Know that the total angle in a pie chart is always equal to 90 degrees.

Find the angle of the red car in the pie chart.

Angle of the red cars$\[ = \frac{{number\,\,of\,\,red\,\,cars}}{{Total\,Cars}} \times {360^ \circ }\]$

                                   $\[\begin{array}{l} = \frac{{40}}{{90}} \times {360^ \circ }\\ = 40 \times 4\\ = {160^ \circ }\end{array}\]$

Hence, the angle of red cars in a pie chart is $160^\circ$.
