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

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

Given:
- Radius \( R = 7.9 \, \text{mm} \)
- \( \pi = 3.14 \)

Let's calculate the volume using these values.

I will now compute it.The volume of the sphere is approximately \( 2064.2 \, \text{mm}^3 \), rounded to the nearest tenth.

Do you have any questions, or would you like further details on the solution?

Here are 5 related questions to expand your understanding:

1. How does changing the radius affect the volume of a sphere?
2. What would be the volume if the radius were doubled?
3. Can you derive the formula for the surface area of a sphere?
4. How does the use of a more accurate value for \( \pi \) (e.g., 3.14159) affect the calculation?
5. What is the relationship between the volume of a sphere and the volume of a cylinder with the same radius and height?

**Tip:** When solving geometry problems involving \( \pi \), keeping more digits for intermediate steps can improve accuracy in final answers.

The radius, R, of a sphere is 7.9 mm. Calculate the sphere's volume, V. Use the value 3.14 for π, and round your answer to the nearest tenth.
