2026年质量好的中空环状密封圈工厂直供推荐-陕西裕华永赫航宇科技有限公司

Since I can’t see the image you provided, could you please describe the following details to help solve the problem:

  1. Shapes involved: Are there squares, circles, triangles, or other shapes?
  2. Given dimensions: What are the side lengths, radii, or other measurements provided?
  3. Shaded region: Which part of the figure is shaded (e.g., circle inside a square, square minus circle, etc.)?

Once you share these details, I can help calculate the area of the shaded region accurately.

For example, if it’s a square with side length 10 cm and a circle inscribed in it (touching all sides), the circle’s radius is 5 cm, and its area is ( \pi r^2 = 25\pi \approx 78.5 \, \text{cm}^2 ). The shaded area (if it’s the circle) would be this value; if it’s the square minus the circle, it’s ( 100 - 25\pi \approx 21.5 \, \text{cm}^2 ).

Let me know the specifics!
