I think that's a Rudbeckia (maybe R. hirta). Ratibida pinnata should have very reflexed petals and a more rounded "cone".

That doesn't look right to me either. The cone is duller and smaller also.

Would you say it's the 'Marmalade' cultivar?

I can't really say, if the petals remain V shaped and droop down than it isn't one I am familiar with.
Most of hirta's have flat petals.

I noticed the petals in both the link images and on mine have two creases in them. Maybe the 100F heat makes mine curl.

Rudbeckia hirta var. pulcherrima.....I saw was a synonym of the 'Marmalade' cultivar somewhere on the web.
Pan down this link/page to 'Rudbeckia hirta var. pulcherrima'
Check out the "photo 1" , It's quite a close match.

Well - I'll give you the creases as similar on yours and that one, your petal tips are split/laciniated -that didn't show up on any of those photos.

Rudbeckia nitida 'Herbstsonne' is similar, but the petals are shorter

Rudbeckia laciniata looks very similar also, and has the split petal tips

Rudbeckia subtomentosa has wider petals.

Xeno - I'll second the R. hirta prognosis. I have several of the other ones on that last post and know them well.
