To find the volume of a sphere, you can use the formula:

\[ V = \frac{4}{3} \pi r^3 \]

where \( V \) is the volume and \( r \) is the radius of the sphere.

Given the diameter of the sphere is 10 meters, the radius \( r \) is half of the diameter:

\[ r = \frac{10}{2} = 5 \, \text{m} \]

Now, plug the radius into the formula:

\[ V = \frac{4}{3} \pi (5)^3 \]
\[ V = \frac{4}{3} \pi (125) \]
\[ V = \frac{500}{3} \pi \]
\[ V \approx \frac{500}{3} \times 3.14159 \]
\[ V \approx 523.6 \, \text{m}^3 \]

Therefore, the volume of the sphere is approximately:

\[ 523.6 \, \text{m}^3 \]

The correct choice from the given options is:

523.6 m cubed
