There is a circular garden in the middle of a square yard. The radius is 4x. The side length of the yard is 20x. What is the area of the part of the yard that is not covered by the circle?

3 answers

well, what is

(20x)^2 - pi(4x)^2 ?
I am fairly sure the answer would be represented by the following polynomial:
-pi(24x)^2

But if anyone else comes up with something they're completely sure is correct, go with that answer instead.
