Answer:

36.3%

Explanation:

To do this, we first find the area of the white part.

Area of white part = area of circle - Area of square.

Area of circle = πr²

Area of circle = π × 4² = 16π cm²

Area of square = (4√2)² = 32 cm²

Area of white portion = 16π - 32 = 18.265 cm²

probability that a randomly selected point within the circle falls in the white area = Area of white portion/area of circle

probability that a randomly selected point within the circle falls in the white area = 18.265/16π ≈ 0.3634

To the nearest tenth gives 36.3%
