The D, otherwise known as the penalty arc, marks an exclusion zone where no outfield players are allowed to stand during the taking of a penalty kick. The distance between any point on the penalty arc, and the penalty spot itself, is 10 yards (9.15 metres).
The D keeps players 10yds from the penalty spot during a PK. If no D was on the top of the penalty box players would be 6yds from the spot.

The arc at the top of the penalty area is not a full half circle. It is scribed out with the penalty mark as its center, and it's there to provide a reference mark that allows players and the officials to know where "10 yards from the ball" is with reference to the penalty mark. Upon a penalty kick, players will take up positions about the top of the penalty box, but outside the arc. The top center of the penalty box is actually a bit closer to the penalty mark than 10 yards. Hence the need for the line. The Laws of the Game require players to be ten yards from the penalty mark (and outside of the penalty box) at the time a penalty kick is taken. Players must remain outside those areas until the ball is touched to (re)initiate play.
If their was a foul in the penalty box during extended time then yh its allowed a penalty kick but only if it before the ended time, if it after then the game ends
During the season they are allowed to have 53 players on their roster. Players that are on the Practice squad or designated as Injured Reserve do not count against this limit.
You are probably referring to the penalty arc which is at the top to the penalty area. It is not exactly a half of a circle.Prior to the taking of a penalty kick all players except the kicker and the opposing goal keeper must be outside of the penalty area and at least 10 yards from the penalty mark. The penalty mark is only 8 yards from the edge of the penalty area! So an extra bit of distance is added to show the players where they must be.
