### Problem Statement

Consider a spherical bubble whose diameter is expanding at the constant rate of 4 cm/s. What is approximately the rate of change of the volume of the bubble when its diameter is 10 cm?

### Multiple Choice Options

1. \[ \text{628.3 } \text{cm}^3/\text{s} \]
2. \[ \text{2513.3 } \text{cm}^3/\text{s} \]
3. \[ \text{5026.6 } \text{cm}^3/\text{s} \] (Selected Option)
4. \[ \text{1047.2 } \text{cm}^3/\text{s} \]
5. \[ \text{8377.6 } \text{cm}^3/\text{s} \]

### Explanation

To determine the rate of change of the volume of the spherical bubble, we need to use the formula relating the volume of a sphere to its radius and the chain rule for differentiation.

The volume \( V \) of a sphere is given by:

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

where:
- \( V \) is the volume,
- \( r \) is the radius of the sphere,
- \( \pi \) is the mathematical constant Pi (approximately 3.14159).

Since the diameter \( D \) is expanding at a constant rate, we have the relationship:

\[ D = 2r \]

Given that \( \frac{dD}{dt} = 4 \text{ cm/s} \), the rate of change of the diameter, we can find the rate of change of the radius \( r \) since \( r = \frac{D}{2} \):

\[ \frac{dD}{dt} = 2 \frac{dr}{dt} \]

\[ 4 \text{ cm/s} = 2 \frac{dr}{dt} \]

\[ \frac{dr}{dt} = 2 \text{ cm/s} \]

We now need to find the rate of change of the volume with respect to time, \( \frac{dV}{dt} \), when the diameter is 10 cm (thus, the radius \( r = 5 \text{ cm} \)):

\[ \frac{dV}{dt} = \frac{dV
