Color the everyday 3D shapes according to the key provided.

Problem Description:

The task is to color the 3D shapes in the image using the provided key. The key specifies the following colors for different 3D shapes:
- Red: Cone
- Blue: Cylinder
- Yellow: Cube

Solution Approach:

1. Identify Each Shape: Carefully examine each shape in the image and determine whether it is a cone, cylinder, or cube.
2. Match with the Key: Use the provided key to assign the correct color to each shape.
3. Color the Shapes: Color each shape according to the identified 3D shape and its corresponding color.

Step-by-Step Analysis:

#### Top Row:
1. Shape 1: This is a cone (pointed at the top with a circular base).
- Color: Red (as per the key).

2. Shape 2: This is a cube (six square faces).
- Color: Yellow (as per the key).

3. Shape 3: This is a cylinder (circular bases with a curved surface).
- Color: Blue (as per the key).

#### Middle Row:
4. Shape 4: This is a cube (six square faces).
- Color: Yellow (as per the key).

5. Shape 5: This is a cone (pointed at the top with a circular base).
- Color: Red (as per the key).

6. Shape 6: This is a cylinder (circular bases with a curved surface).
- Color: Blue (as per the key).

#### Bottom Row:
7. Shape 7: This is a cylinder (circular bases with a curved surface).
- Color: Blue (as per the key).

8. Shape 8: This is a cylinder (circular bases with a curved surface).
- Color: Blue (as per the key).

9. Shape 9: This is a cone (pointed at the top with a circular base).
- Color: Red (as per the key).

Final Coloring:

- Red: Shapes 1, 5, and 9 (cones).
- Blue: Shapes 3, 6, 7, and 8 (cylinders).
- Yellow: Shapes 2 and 4 (cubes).

Final Answer:

\[
\boxed{
\text{Red: Shapes 1, 5, 9; Blue: Shapes 3, 6, 7, 8; Yellow: Shapes 2, 4}
}
