What is the literacy rate of Marietta,Georgia or where can i find what the literacy rate is?
I have not yet found anything more detailed than Cobb County, but the Census Bureau came up with these figures projected from the 1-in-6 exhaustive survey and the number/percent of people with high school or college degrees based on the total returns (about halfway down the page).
You might be able to dig through the whole Census Bureau website to see whether one of their exhaustive .pdfs carries figures for Marietta, alone. (If I were guessing where to find stuff like that (since their State&County QuickFacts did not get down to that level), I would start with the pages addressed to help Industry (since education is a key factor in relocating plants or starting new ones). The key phrase in the Census documents is Educational Attainment, but most of the easy hits on that phrase are tabled nationally, not locally.
You might find more places to look on this page.
This appears to be the info you’re looking for:

This is the most recent, comprehensive national study of literacy of which I’m aware. The Census Bureau does not directly estimate literacy rates, but can only provide information about educational attainment and such.
Note that “literacy rate” is a term that needs definin’, as it means different things to different groups.
