Good evening. I hope you are well. Attached as a JPG is my question.

**Problem 11.10:** Find the arc-length from \((-3, 4)\) counter-clockwise to \((4, 3)\) along the circle \(x^2 + y^2 = 25\). 

**Explanation:**

- The circle equation \(x^2 + y^2 = 25\) represents a circle centered at the origin with a radius of 5.
- The problem asks for the arc-length between two points, \((-3, 4)\) and \((4, 3)\), moving counter-clockwise along the circumference of the circle.

To solve this, you would typically:

1. Identify the angles corresponding to each point on the circle using trigonometry.
2. Calculate the angular distance between these angles.
3. Use the formula for arc length, which is \( s = r\theta \), where \( r \) is the radius, and \( \theta \) is the angular distance in radians. For a complete understanding, students might need guidance on converting from Cartesian to polar coordinates and the methods for calculating angles based on specific points.
