The square below has side 5x. Find the area of the square remaining after a circle of radius 2x is removed from the square; in other words, find the area of the shaded region in factored form.

Answer:
12.43x²
Step-by-step explanation:
area circle: pi×(2x)²
= 4pi×x²
area square:
5x×5x= 25x²
colored area: area square- area circle
=25x²-4pi×x²
≈12.43x²
