The amount a cow eats in the pasture is not measured by "pounds of pasture" as pasture includes the plants and the soil. The amount of forage biomass or just forage is what you should be referring to. So, a typical 1000 lb cow will eat around 2.5% of her body weight in dry matter, which is around 26 lbs DM.
Consumption varies throughout the year, but the average is around 12.3/day.

Yes. Hay is THE main staple of any cow's diet when not on pasture.
No. When you drive by a cow pasture notice all the tufts of grass standing around the pasture. This is where old cow patties lie because they avoid grazing the grass that grows around these patties. But that occurs only if they are set to continuously graze a pasture.
Probably cause the grass on the other side of the fence is tastier than the grass that's in the pasture. Cows will reach through the fence if the grass in the pasture is down, or they don't want to eat a particular species of grass that is in the pasture.

It depends on how much this "average" cow weighs and whether you're referring to the amount of ready-to-eat meat on a cow or the hot-carcass weight of that "average" cow. It also depends on whether you're referring to a "cow" or a cow, its type and breed.
Yes. If you are hand-broadcasting seed over a pasture or in spots where a cow can eat it, she will defecate it out. This seed will grow from this manure and thus repopulate the current stand in the pasture.
That all depends on the type of cow, or "cow." Dairy cows and cattle are often find in sheds or what are known as "cow sheds," byres, or barns, and beef cattle are found in a pasture, range, corral, pen or, depending on the weather conditions, a loafing shed. Dairy cattle are also found on pasture depending on the season and grazing conditions.
A cow will typically eat 2.5% of her body weight of ration DM per day. As to what to feed her, hay, silage, grass and a little grain is the main rations to consider feeding a cow. When a cow is on pasture, she usually doesn't need any other supplementation except a bit of mineral.
