![### Calculus Problem: Finding Arc Length of Enclosed Region
#### Problem Statement:
Given a region \( R \) enclosed by the curves
\[ y = 1 + \sin\left(\frac{\pi x}{4}\right), \quad y = 4 - \frac{(x - 2)^2}{4} \quad \text{and} \quad x = 2 \]
as shown below.
#### Graph Description:
The graph shows two curves intersecting in the \( xy \)-plane.
1. **Curve 1:** \( y = 1 + \sin\left(\frac{\pi x}{4}\right) \) which starts from the point \((-2, 0)\) and curves upwards.
2. **Curve 2:** \( y = 4 - \frac{(x - 2)^2}{4} \) which is a downward parabola starting from the point \( (2, 4) \) and ending at point \( (2, 2) \).
The region \( R \) is enclosed between these two curves and the vertical line \( x = 2 \).
#### Task:
Set up (and do not simplify) the (sum of) definite integral(s) equal to the following:
1. Arc length of the curve
\[ y = 4 - \frac{(x - 2)^2}{4} \]
bordering the region \( R \).
#### Solution:
The arc length \( L \) of a function \( y = f(x) \) from \( x = a \) to \( x = b \) is given by:
\[ L = \int_{a}^{b} \sqrt{1 + \left(\frac{dy}{dx}\right)^2} \, dx \]
In this problem, we want to find the arc length of the curve \( y = 4 - \frac{(x - 2)^2}{4} \). Therefore, we need to compute \( \frac{dy}{dx} \):
\[ y = 4 - \frac{(x - 2)^2}{4} \]
Taking the derivative with respect to \( x \),
\[ \frac{dy}{dx](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F610d65bd-822d-435d-bd07-52365ff393da%2F4d6374a6-9ece-44bb-b802-cf548cdcb569%2Fev4ivs_processed.png&w=3840&q=75)
