Answer:
0.36
Explanation:
The area of the square is the square of its side length:
As = (4√2)² = 32
The area of the circle is given by ...
Ac = πr² = π(4²) = 16π
The white area as a fraction of the circle area is ...
(Ac -As)/Ac = (16π -32)/(16π) = 1 -2/π ≈ 0.36
The probability of hitting a white area in the circle is about 0.36.
