It depends on what you mean by "big". It has a radius of 600 inches.
Any number you like. You can have a tiny circle with a tiny diameter or a huge big circle with a big diameter. The diameter is simply the "width" of the circle. It is the length of the line from one side to the other which passes through the centre.
It is as big as a big potato chip
It will be a big mistake.
"One and a half inches" is approximately the same length as 38.1 millimeters (rounded), regardless whether it refers to a piece of string, a measurement of a geographic figure, or a blade of grass. A circle whose diameter is one and a half inches has an area of 1.767 square inches. (rounded)
it is 6 inches diameter
The circle has a diameter of 6.366 inches.
Twelve inches is a length. It can be a diameter, but if it is a diameter, you would simply say 'The circle is 12 inches diameter'. So; how big is it - it is 12 inches.

2 7/8 inches to 3 inches in diameter
Oh, dude, this is like basic math 101. The diameter of a circle is just twice the radius, so if the radius is 1 meter, the diameter is 2 meters. It's like the circle's way of saying, "I'm just twice as big as my radius, no big deal."
A 50-meter diameter is equivalent to the distance across a circle from one edge to the other passing through the center, measuring 50 meters in length. In terms of area, a circle with a 50-meter diameter would have a radius of 25 meters and an area of approximately 1,963.5 square meters (πr^2). This size can be visualized as a circle with a radius of 25 meters or a little over 82 feet.
2 7/8 inches to 3 inches in diameter
The diameter is 14 / 3.141592654 = 4.4563384 inches.
