Maybe ray and circumference would be enough.

Transform your ray by the inverse of your cylinder matrix this way you have the ray in the local space of the cylinder. Then you can use the equation to find the intersection. https://forums.khronos.org/showthread.php/55954

Transform position and direction (and normalize)

Vector2.Transform() // applies the entire Matrix to the vector
Vector2.TransformNormal() // only applies the Scale and Rotational parts of the Matrix to the vector.
