Question

1. Identify the Given Values:
- Radius (\( r \)) = 12 mm
- Approximation for \( \pi \) = 3.14

2. Substitute the Values Into the Formula:

\[
V = (4)/(3) * 3.14 * (12)^3
\]

3. Calculate \( 12^3 \) (12 cubed):

\[
12^3 = 12 * 12 * 12 = 1728
\]

4. Plug the Values into the Formula:

\[
V = (4)/(3) * 3.14 * 1728
\]

5. Multiply the Values:

- First, calculate the multiplication: \( 4 * 3.14 * 1728 \)

\[
4 * 1728 = 6912
\]

\[
6912 * 3.14 = 21727.68
\]

6. Divide by 3:

\[
(21727.68)/(3) \approx 7234.56
\]

7. Round to the Nearest Hundredth:

- The volume of the chocolate truffle, rounded to the nearest hundredth, is 7234.56 mm\(^3\).

Therefore, the amount of chocolate in the spherical truffle is approximately 7234.56 mm\(^3\).

Your calculations for the volume of the spherical chocolate truffle are generally correct, but let’s reorganize and verify the computation step-by-step:

1. **Identify the Given Values:**
- Radius (\( r \)) = 12 mm
- Approximation for \( \pi \) = 3.14

2. **Substitute the Values Into the Formula for Volume of a Sphere:**

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

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

Substituting the known values:

\[
V = \frac{4}{3} * 3.14 * (12)^3
\]

3. **Calculate \( 12^3 \) (12 cubed):**

\[
12^3 = 12 * 12 * 12 = 1728
\]

4. **Plug the Values into the Formula:**

\[
V = \frac{4}{3} * 3.14 * 1728
\]

5. **Multiply the Values:**

- Start by calculating \( 4 * 1728 \):

\[
4 * 1728 = 6912
\]

- Next, multiply \( 6912 * 3.14 \):

\[
6912 * 3.14 = 21727.68
\]

6. **Divide by 3:**

Now, divide \( 21727.68 \) by 3 to finalize the volume:

\[
V = \frac{21727.68}{3} \approx 7242.56
\]

7. **Round to the Nearest Hundredth:**

The volume of the chocolate truffle, rounded to the nearest hundredth, is approximately **7242.56 mm³**.

Therefore, the amount of chocolate in the spherical truffle is approximately **7242.56 mm³**.

Your initial rounding step was not accurate; the correct final answer is **7242.56 mm³**.
