How many surfaces does a coin have?
A coin is considered to be cylindrical in shape.
Answer: A coin has one curved and two flat surfaces.
Let's know about the surfaces of a coin.
In mathematics, a coin is in the shape of a cylinder. It has 'two' flat faces and one curved surface (edge of the coin).
A coin is generally circular in shape because the height (thickness) of the coin is very less when compared to its diameter.
Thus, a coin has one curved and two flat surfaces.
