A water tower has a height of 25 meters and a width of 16 meters.

What is the volume of the water tower? Use 3.14 for pi. (1 point)
5,024 cubic meters
15,700 cubic meters
20,096 cubic meters
7,850 cubic meters

To find the volume of the water tower, we can model it as a cylinder. The formula for the volume \( V \) of a cylinder is given by:

\[ V = \pi r^2 h \]

where \( r \) is the radius, and \( h \) is the height.

Given:

  • Height \( h = 25 \) meters
  • Width (diameter) \( d = 16 \) meters

First, we need to find the radius \( r \):

\[ r = \frac{d}{2} = \frac{16}{2} = 8 \text{ meters} \]

Now, we can substitute the values into the volume formula:

\[ V = \pi r^2 h = 3.14 \times (8)^2 \times 25 \]

Calculating \( r^2 \):

\[ (8)^2 = 64 \]

Now substituting back into the volume formula:

\[ V = 3.14 \times 64 \times 25 \]

Calculating \( 64 \times 25 \):

\[ 64 \times 25 = 1600 \]

Now calculating the volume:

\[ V = 3.14 \times 1600 \]

Calculating \( 3.14 \times 1600 \):

\[ V = 5024 \]

Thus, the volume of the water tower is:

\[ V = 5,024 \text{ cubic meters} \]

Therefore, the correct answer is 5,024 cubic meters.
