Gina wants to duplicate this circle graph. Which of the following is closest to the measure of the central angle of the
"walking" sector?

Respuesta :

Using proportions, it is found that the central angle of the walking sector is of 36º.

  • This question can be solved by proportions, using a rule of three.
  • The angle corresponding to 100% = 1 is of 360º, while we want to find the angle corresponding to the walking sector, which is of 10% of the circle.

Hence, the rule of three is:

1 - 360º

0.1 - x

Applying cross multiplication:

[tex]x = 360(0.1) = 36[/tex]

The central angle of the walking sector is of 36º.
