**Problem 1**

Let \(\vec{A} = x^2 \hat{a}_x + y^2 \hat{a}_y + z^2 \hat{a}_z\) and let \(S\) be a surface defined by \(\rho \leq h\); \(a \leq z \leq b\).

a. Express \(\vec{A}\) in cylindrical coordinates.

b. Find \(\oint_S \vec{A} \cdot d\vec{s}\).

c. Find \(\nabla \cdot \vec{A}\) in cylindrical coordinates.

d. Find \(\int_V \nabla \cdot \vec{A} \, dv\) where \(V\) is the volume enclosed by \(S\).
