# The diameter of a U.S quarter is 24.26 millimeters. How long is a line of 37 quarters laid edge to edge?

The total distance is equal to the number of quarters multiplied by the quarter's diameter when they are arranged edge to edge.

To calculate the length of a line of 37 quarters laid edge to edge, you would multiply the diameter of a single quarter by the number of quarters and subtract the overlap.

First, calculate the total diameter of the quarters laid edge to edge:

[ \text{Total diameter} = \text{diameter of a single quarter} \times (\text{number of quarters} - 1) ]

[ \text{Total diameter} = 24.26 , \text{mm} \times (37 - 1) ]

[ \text{Total diameter} = 24.26 , \text{mm} \times 36 ]

[ \text{Total diameter} = 872.16 , \text{mm} ]

However, this only accounts for the edges touching, so you need to add the diameter of one quarter for the overlap:

[ \text{Total length} = 872.16 , \text{mm} + 24.26 , \text{mm} ]

[ \text{Total length} = 896.42 , \text{mm} ]

So, the total length of a line of 37 quarters laid edge to edge is 896.42 millimeters.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
