Calculate the volume of the concrete pillar in the figure.

 
Select an answer:
 
**44 000 m3**
 
**16 461.95 m3**
 
**1 108 m3**
 
**1 108.86 m3**
 
**6 285.7 m3**

To determine the volume of a concrete pillar, we typically need to know its shape and dimensions. Since the figure is not provided here, I'll outline the process generally:

1. **Identify the shape of the pillar:** Common shapes include cylindrical, rectangular prism, and others.

2. **Measure the dimensions:** For a cylinder, we need the radius (or diameter) and height. For a rectangular prism, we need the length, width, and height.

3. **Use the appropriate volume formula:**
   - **Cylinder:** \( V = \pi r^2 h \)
   - **Rectangular Prism:** \( V = l \times w \times h \)

Without the specific figure, let's assume a common shape and calculate based on provided options.

### Let's consider each option based on possible dimensions:

#### **Cylindrical Pillar Example:**

Assume the pillar is a cylinder:
\[ V = \pi r^2 h \]

1. **Check the feasibility of each volume:**
   - For \( 44,000 \, m^3 \): 
     \( \pi r^2 h \approx 44,000 \)
   - For \( 16,461.95 \, m^3 \):
     \( \pi r^2 h \approx 16,461.95 \)
   - For \( 1,108 \, m^3 \):
     \( \pi r^2 h \approx 1,108 \)
   - For \( 1,108.86 \, m^3 \):
     \( \pi r^2 h \approx 1,108.86 \)
   - For \( 6,285.7 \, m^3 \):
     \( \pi r^2 h \approx 6,285.7 \)

Using the options, check if they fit reasonable dimensions for a cylindrical shape:

### Example Calculation:
Let's assume a typical size for easy calculation:

- Suppose \( r = 5 \, m \) and \( h = 15 \, m \):
  \[ V = \pi (5^2) (15) \approx 3.14159 \times 25 \times 15 \]
  \[ V \approx 3.14159 \times 375 \approx 1,178.1 \, m^3 \]

### Matching Option:
The closest matching volume from the given options is **1,108.86 m^3**, suggesting this as the most likely correct answer if the shape and dimensions match typical cylindrical pillars.

Thus, the correct answer appears to be:
\[ \boxed{1,108.86 \, m^3} \]
