There is a circular garden in the middle of a square yard. The radius of the circle 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?

4x(5)
8x^2 (5 – )
16x(25 + )
16x^2 (25 – )
The area of the yard is given by the side length squared, so the area of the yard is (20x)^2 = 400x^2.
The area of the circle is given by the formula A = πr^2, where r is the radius. So the area of the circle is π(4x)^2 = 16πx^2.
To find the area of the part of the yard that is not covered by the circle, we subtract the area of the circle from the area of the yard. Therefore, the area of the part of the yard that is not covered by the circle is 400x^2 - 16πx^2.
Therefore, the correct answer is 400x^2 - 16πx^2, or option choice (3) 16x^2(25 - π).
