Question
**Problem Statement:**

Compute the line integral of the vector field **F** = ⟨3y, -3x⟩ over the circle defined by the equation \(x^2 + y^2 = 81\), oriented clockwise.

\[
\int_{C} \mathbf{F} \cdot d\mathbf{s} = 
\]

**Details:**

- Vector field **F** is given with components 3y in the x-direction and -3x in the y-direction.
- The path of integration is a circle with radius 9 (since \(\sqrt{81} = 9\)), centered at the origin.
- The orientation for the line integral is clockwise.

**Graph/Diagram Explanation:**

There are no graphs or diagrams provided in this image. The problem primarily involves performing calculations related to the line integral along a circular path with defined vector field properties and orientation.
