### Explanation
The problem requires finding the arc length of a parametric curve defined by the equations \( x = 3 \cos(7t) \) and \( y = 3 \sin(7t) \) within the given range for the parameter \( t \).
#### To find the arc length of a parametric curve:
Use the formula for the arc length \( L \) of a parametric curve \((x(t), y(t))\) from \( t = a \) to \( t = b \):
\[ L = \int_{a}^{b} \sqrt{\left( \frac{dx}{dt} \right)^2 + \left( \frac{dy}{dt} \right)^2} \, dt \]
Given:
- \( x = 3 \cos(7t) \)
- \( y = 3 \sin(7t) \)
- \( 0 \leq t \leq \frac{\pi}{28} \)
#### Steps to solve:
1. Find \( \frac{dx}{dt} \) and \( \frac{dy}{dt} \):
\[
\frac{dx}{dt} = \frac{d}{dt} (3 \cos(7t)) = 3 \cdot (-7 \sin(7t)) = -21 \sin(7t)
\]
\[
\frac{dy}{dt} = \frac{d}{dt} (3 \sin(7t)) = 3 \cdot (7 \cos(7t)) = 21 \cos(7t)
\]
2. Substitute \( \frac{dx}{dt} \) and \( \frac{dy}{dt} \) into the arc length formula:
\[
L = \int_{0}^{\frac{\pi}{28}} \sqrt{(-21 \sin](https://content.bartleby.com/qna-images/question/41a4f8e2-50b1-40c5-ab3a-6358b729bd6f/4b71b192-6a30-4525-bb78-100e3780a054/a2y67d9_processed.png)
