This is a multiple figure problem. The key to these problems is to look for elements that are common to both shapes.
Diagonal of the square is the diameter of the circle.
We know each side of the square is 4.
Because of our 45-45-90 triangle rule, that means the diagonal of the square is 4 √ 2 (aka the diameter of the circle)
So the radius of the circle is 2 √ 2
Now all we need is the area of the circle, which is π * (2 √ 2) squared, or 8π
Answer: C
