Question

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

Answer 1

Hint: Here we are given a diameter of one quarter and we are asked to find for $ 37 $ quarters, so here we will use the multiplication to get the required resultant value.

Complete step-by-step answer:
Given that the diameter of a U. S. quarter is $ 24.26 $ millimeters
Also, given that the quarters are placed edge to edge to the total distance which is the number of quarters multiplied by the diameter of the quarter.
Therefore, the length of a line of $ 37 $ quarters which are laid edge to edge is equal to
 $ = 37 \times 24.26 $
Multiply the above expression and simplify it –
 $ = 897.62\;mm $
This is the required solution.
So, the correct answer is “897.62 mm”.

Note: Do not forget to write the appropriate units after getting the resultant value. Always check the given units in the question and then start solving them. As there is a lot of difference between the one centimeter and one meter. All the given units should be in the same format.
