half an inch diameter van
2 inches. the radius is half of the diameter

The area of a coin can be calculated using the formula for the area of a circle, which is A = πr², where A is the area and r is the radius of the coin. To find the area, you first need to measure the radius (half of the diameter) of the coin. Once you have the radius, square it and multiply by π (approximately 3.14). For example, if a coin has a diameter of 2 inches, its radius would be 1 inch, resulting in an area of approximately 3.14 square inches.
A 12 mm circle has a diameter of 12 millimeters, which is slightly less than half an inch (approximately 0.47 inches). The radius, which is half the diameter, is 6 mm. In terms of area, the circle has an area of about 113.1 square millimeters. This size is comparable to the diameter of a large button or a small coin.
No, the US mint has never minted a 2 inch silver coin for circulation or for bullion purposes. The largest silver coin in diameter that I know of that was produced by the US mint would be the American Silver Eagle with a diameter of about 1.58 inches and the US silver dollars which have a diameter of 1.5 inches.
