To determine the correct answer, let’s analyze the common problem scenarios matching the given options:

Key Observations:

The options involve combinations of integers and multiples of π, suggesting a geometric figure (like a square and circle) where the shaded area is the difference between their areas.

Common Scenario: Square with Inscribed Circle

Suppose we have a square of side length 8:

• Area of the square = (8^2 = 64).
• The inscribed circle has diameter equal to the square’s side (8), so radius = 4.
• Area of the circle = (\pi r^2 = \pi(4)^2 = 16\pi).
• Shaded area (square minus circle) = (64 - 16\pi).

This matches Option A.

Answer: A
