This would be much easier to answer if you would use a conventional representation of ordered pairs:
... (-1, -2) instead of "begin ordered pair negative 1 comma negative 2 end ordered pair"
The area of a circle is equal to the radius squared times pie, basically:

The radius is 3, so we multiply 3 times 3 times pie to get the area.
You're gonna want to plug in the following into a calculator:

After getting 28.26 from such calculator, you need to round to the tenths place. In this number, the tenths place is the 2 next to the decimal on the right. Because the number after the 2 is a 6, that means we need to simplify the answer to (28.3). When you are rounding a number, you look at the number to the right, if it is 5 or bigger, add one and remove the rest, if it is less than 5, just get rid of the rest and leave it as it is.
Answer:
Yes
Step-by-step explanation:
A statistical question is one that can be asked and expected to receive answers that may vary - in other words, where the data from each participant is different.
Here, the question is "How many times did you ride the Ferris wheel today?” Obviously, it's almost impossible that each person asked rode the Ferris wheel the same number of times. Some people may say "once", others may say "three times", and still others might not have ridden it at all.
Given the differences in all these answers, we can say that this IS a statistical question.
Hope this helps!
