Alright, I need to solve these problems involving the calculation of arc length given the radius and the angle. Let's go through each one step by step.

**Problem 1:**
Given:
- $$ r = 3 \, \text{cm} $$
- $$ \theta = \frac{n}{3} $$

First, I need to understand what $$ \theta = \frac{n}{3} $$ represents. It seems like $$ n $$ is a variable, but without additional information, it's unclear what $$ n $$ is. Maybe $$ n $$ is a specific value or a parameter that needs to be defined. For now, I'll assume $$ n $$ is a constant angle in radians. If $$ n $$ is in degrees, I'll need to convert it to radians to use the arc length formula.

The formula for arc length $$ s $$ is:
$$
s = r \times \theta
$$
If $$ \theta $$ is in radians, then:
$$
s = 3 \, \text{cm} \times \frac{n}{3} = n \, \text{cm}
$$
But since $$ n $$ is undefined, I can't compute a numerical value for the arc length. Maybe there's a missing piece of information here.

**Problem 2:**
Given:
- $$ r = 5 \, \text{cm} $$
- $$ \theta = \frac{3\pi}{2} $$

Here, $$ \theta $$ is given in radians, which is good. Plugging into the arc length formula:
$$
s = 5 \, \text{cm} \times \frac{3\pi}{2} = \frac{15\pi}{2} \, \text{cm} \approx 23.562 \, \text{cm}
$$
This matches the provided answer of $$ 12,043 \, \text{cm} $$, which seems unusually large. Maybe there's a typo in the problem statement or the answer.

**Problem 3:**
Given:
- $$ r = 2 \, \text{cm} $$
- $$ \theta = \frac{5\pi}{4} $$

Again, $$ \theta $$ is in radians. Calculating the arc length:
$$
s = 2 \, \text{cm} \times \frac{5\pi}{4} = \frac{10\pi}{4} = \frac{5\pi}{2} \, \text{cm} \approx 7.854 \, \text{cm}
$$
The provided answer is $$ 15.499 \, \text{cm} $$, which is double the calculated value. This discrepancy suggests that either the angle was doubled or there's an error in the problem statement.

**Problem 4:**
Given:
- $$ r = 4 \, \text{cm} $$
- $$ \theta = 222^\circ $$

First, convert $$ \theta $$ to radians:
$$
\theta = 222^\circ \times \frac{\pi}{180} = \frac{222\pi}{180} = \frac{37\pi}{30} \, \text{radians}
$$
Now, calculate the arc length:
$$
s = 4 \, \text{cm} \times \frac{37\pi}{30} = \frac{148\pi}{30} \approx 15.562 \, \text{cm}
$$
The provided answer is $$ 13,744 \, \text{cm} $$, which is significantly larger. This indicates a possible error in the problem or the answer.

**Problem 5:**
Given:
- $$ r = \frac{5}{2} \, \text{cm} $$
- $$ \theta = 315^\circ $$

Convert $$ \theta $$ to radians:
$$
\theta = 315^\circ \times \frac{\pi}{180} = \frac{315\pi}{180} = \frac{7\pi}{4} \, \text{radians}
$$
Calculate the arc length:
$$
s = \frac{5}{2} \, \text{cm} \times \frac{7\pi}{4} = \frac{35\pi}{8} \approx 13.744 \, \text{cm}
$$
This matches the provided answer of $$ 13,744 \, \text{cm} $$, which seems unusually large. It's possible that the angle was intended to be in radians, leading to this discrepancy.

**Problem 6:**
Given:
- $$ r = 4.6 \, \text{cm} $$
- $$ \theta = 150^\circ $$

Convert $$ \theta $$ to radians:
$$
\theta = 150^\circ \times \frac{\pi}{180} = \frac{150\pi}{180} = \frac{5\pi}{6} \, \text{radians}
$$
Calculate the arc length:
$$
s = 4.6 \, \text{cm} \times \frac{5\pi}{6} = \frac{23\pi}{6} \approx 12.043 \, \text{cm}
$$
The provided answer is $$ 23,562 \, \text{cm} $$, which is much larger. This suggests a possible error in the problem or the answer.

**Summary:**
- **Problem 1:** Cannot determine the arc length without additional information.
- **Problem 2:** Arc length is approximately $$ 23.562 \, \text{cm} $$, but the provided answer is $$ 12,043 \, \text{cm} $$.
- **Problem 3:** Arc length is approximately $$ 7.854 \, \text{cm} $$, but the provided answer is $$ 15.499 \, \text{cm} $$.
- **Problem 4:** Arc length is approximately $$ 15.562 \, \text{cm} $$, but the provided answer is $$ 13,744 \, \text{cm} $$.
- **Problem 5:** Arc length is approximately $$ 13.744 \, \text{cm} $$, but the provided answer is $$ 13,744 \, \text{cm} $$.
- **Problem 6:** Arc length is approximately $$ 12.043 \, \text{cm} $$, but the provided answer is $$ 23,562 \, \text{cm} $$.
