Thread: 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.
2.

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

Have you started with a sketch?

Well thats another problem.. I don't know how it should look like, i don't know how to plot it in Mathmatica..

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.

But how would it look like? Radius etc.
