    Double integration of 2 cylinders

    I have to sketch the domain of the integration and evaluate the given iterated integrals.

    I have 2 cylinders
    1. x^2+y^2 = a^2
    2. y^2+z^2 = a^2

    The biggest problem for me is to write the integration, with the boundaries?
    How do i find them?

    The first is made of circular cross-sections in the x-y plane of radius a units, extending along the z axis.

    The second is made of circular cross-sections in the y-z plane of radius a units, extending out in the x axis.
