If there are 4 ninth graders total, and 3 of them don’t like action, the probability of a randomly selected ninth grader not preferring action is 3/4.
If there are more than 4 ninth graders total - the survey suggests that approximately 3/4 ninth graders do not prefer action. We can then approximate the probability that a randomly selected ninth grader does not prefer action as 3/4.

Answer:

First, let's find how far away the pier is.

Using the distance formula, we can see that the pier is \sqrt{58} units away.

So, the radius is sqrt 58.

Area = pi (r)^2

So,  the area is 182.82 square units.
