Question

The data below show the colors of bikes owned by students in a class. How would you calculate the angle of the wedge for "red"? A. Multiply 30 by 100%. B. Multiply 0.30 by 100°. C. Multiply 0.30 by 360°. D. Multiply 0.15 by 100°.

Answer 1

Given:

The percentage of students who have red colour bikes is 30%.

To calculate:

The angle measure.

Explanation:

First cancelling the percentage, we will get,

$\frac{30}{100}=0.30$

We know that the central angle is 360 degrees.

So, the angle measure of red is obtained by

$0.30\times360^{\circ}$

That is, It is obtained by multiplying 0.30 by 360 degrees.

Final answer: Option C.

Multiply 0.30 by 360 degrees.
