The diameter, D, of thr sphere is 18.8 m. Calculate the spheres volume, V.

To calculate the volume \( V \) of a sphere, we can use the formula:

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

where \( r \) is the radius of the sphere. The radius is half of the diameter.

Given that the diameter \( D = 18.8 \) m, we can find the radius:

\[
r = \frac{D}{2} = \frac{18.8}{2} = 9.4 \text{ m}
\]

Now, we can substitute the value of \( r \) into the volume formula. Using \( \pi \approx 3.14 \):

\[
V = \frac{4}{3} \times 3.14 \times (9.4)^3
\]

First, calculate \( (9.4)^3 \):

\[
9.4^3 = 9.4 \times 9.4 \times 9.4 = 830.584
\]

Now, substitute \( 9.4^3 \) into the volume formula:

\[
V = \frac{4}{3} \times 3.14 \times 830.584
\]

Next, calculate \( \frac{4}{3} \times 3.14 \):

\[
\frac{4}{3} \times 3.14 \approx 4.18666667 \text{ (approximately 4.19)}
\]

Now, continue calculating the volume:

\[
V \approx 4.18666667 \times 830.584 \approx 3477.797
\]

Finally, round this value to the nearest tenth:

\[
V \approx 3477.8 \, \text{m}^3
\]

Therefore, the volume of the sphere is approximately:

\[
\boxed{3477.8 \, \text{m}^3}
\]
