Here is my problem. I don't fully understand Gauss' law so any assistance there would be greatly appreciated

Charge is distributed uniformly throughout the volume of an infinitely long cylinder of radius R = 4.00×10-2 m. The charge density is 1.00×10-2 C/ m3. What is the electric field at r = 2.00×10-2 m?

(in N/C)

2. Relevant equations

3. The attempt at a solution

I understand that gauss' law is the integral EdA and that the E for a cylinder is lamda/2pi(E0)r , but I don't understand it for an infinite cylinder
