How many surfaces does a coin have?
State the number of surfaces of a coin
In mathematics, a coin is in the shape of a cylinder. It has 'two' flat circular faces in upper and lower sides and one curved surface (i.e., edge of the coin).
A coin is generally circular in shape as the height (thickness) of the coin is very less when compared to its diameter.
Thus, a coin has one curved and two flat circular surfaces.
Hence, a coin has surfaces.
