Hello peeps!

I need help with setting up the integrals. I know how to evaluate but I need help setting it up!

1 ) The region common to the interiors of the cylinders x^2 + y^2 = 100 and x^2 + z^2 = 100. (cylindrical coordinates)

And also problems(Headbang)(spherical coordinates), 18 (cylindrical coordinates) in the attachment.14

please elaborate how you set up the integral on #14.
