**Problem Statement:**
In circle N with \( m \angle MNP = 156 \) and \( MN = 10 \) units, find the length of arc MP. Round to the nearest hundredth.

**Diagram Explanation:**
This is a simple circle diagram with three points, M, N, and P:
- N is the center of the circle.
- M and P are points on the circumference of the circle.
- The angle \( \angle MNP = 156^\circ \).
- The radius MN is given as 10 units.

The problem requires you to calculate the length of arc MP and round the answer to the nearest hundredth.

**Solution Steps:**
1. Determine the radius of the circle, which is given as 10 units.
2. Recognize that the given angle \( \angle MNP = 156^\circ \) is the central angle subtending the arc MP.
3. Use the formula for the length of an arc, \( L = \theta \cdot r \), where \( \theta \) is the central angle in radians and \( r \) is the radius.

Convert the central angle from degrees to radians:
\[ \theta = 156^\circ \times \frac{\pi}{180^\circ} = \frac{156\pi}{180} = \frac{13\pi}{15} \text{ radians} \]

4. Calculate the arc length:
\[ L = \frac{13\pi}{15} \cdot 10 \text{ units} \]
\[ L = \frac{130\pi}{15} \text{ units} \]
\[ L \approx 27.20 \text{ units (rounded to the nearest hundredth)} \]

Thus, the length of arc MP is approximately 27.20 units.
