Question 624552
There are 10/0.25 = 40 quarters total.


The total height of the stack of quarters is h = 40*1.75 = 70 mm


The volume is then...


V = pi*r^2*h


V = pi*12^2*70


V = 10080pi   <font color="blue"><< ------- Exact Volume</font>


V = 10080(3.14159)  


V = 31667.2272   <font color="red"><< ------- Approximate Volume</font>
