hi does anyone know where you can buy paper disposable cake pans rectangular and round shapes approx 10" width and 3" depth?

thanks!

What would you need them for? I never buy cakes, but also do not remember where I have ever seen them before

Do you mean like these? I've never seen them in the US, this company sells all kinds of sizes too. 

Check out these sites. I didn't check to see all of the sizes offered:
