Answer:

C) 118.8; 28.8

Step-by-step explanation:

for eating, it didn't make sense for it to be 288 degrees, so i eliminated the two off the list. For sleeping, it made more sense for it to be a 118.8 degree angle, so I narrowed it down to C.

The central angle for sleeping is 118.8 degrees and the central angle for eating is 28.8 degrees.

What is the central angle of a pie chart?

The angle formed by an arc of the circle at the center of the circle is called central angle of a pie chart.

How to find the central angle of a pie chart?

central angle = [tex]\frac{sector}{100}[/tex] × 360

According to the given question

We have a pie chart

In which, time spend by students in different activities is given.

Now,

The measure of central angle for sleeping is given by

Central angle for sleeping = [tex]\frac{sector}{100}[/tex] × 360

⇒ Central angle for sleeping =[tex]\frac{33}{100}[/tex] × 360 = 118.8 degrees.

Similarly,

The measure of central angle for eating is given by

Central angle for eating = [tex]\frac{8}{100}[/tex] × 360 = 28.8 degrees

Hence, first option is correct.
