Quarter Coin Display

Calculating the Volume of a quarter in cm3:

Volume =thickness x x radius2 radius = ½ diameter  = pi = 3.142

The thickness of the quarter is __.1___________

The diameter of the quarter is ________2.5_____

This means that the radius is _________1.25_____

Volume= ____.1_____x 3.142 x 1.25 = .39275
thicknesspiradius2 calculator display



Volume = .4
I have that and i know is wrong , there is something that i am doing wrong but i don't know what is it

volume = thickness x pi x r^2

you forgot to square your radius in your calculation

the correct answer would be

volume = .1cm x 3.142 x 1.25cm x 1.25cm = .4909 cm3

a good way to check when in doubt is to see whether the units multiply up correctly

It is round, holds only one quarter and is used to transport coins through the mail. I want to remove it to place into a display Dansco album. Any help would be greatly appreciated.

Put it in the freezer until the quarter shrinks, then tap it on the countertop.

Hello, does anyone know the code to make a functional coin counter in vb? so, for example, i enter $5.92 displays:
2 toonie(s)
1 loonie(s)
3 quarter(s)
1 dime(s)
1 nickel(s)
2 pennie(s)
your help will be greatly appreciated.
p.s. 10 pts if i choose ur answer : )

You don't need to do any looping or any if statements and in this case NOT using a loop will make it easier to see what you are doing.

I am not sure what you mean by toonies and loonies so I just processed the cents. The same technique can be used for your dollar values.


A simple wayto process this is to use Integer math which doesn't use decimal points. This is like when you first learned division in school where 5 divided by 2 equaled 2 remainder 1

Intger division 5 \ 2 (note the different slash) = 2
And to get the remainder we use modulo division which returns the remainder
5 mod 2 = 1 (the remainder)

Once you compute the number of quarters, the remainder is what you will use to see how many dimes are in the remainder. This is why the ammount is recalulated by using MOD. That changes the amount for the next calculation.


Note the coins are computed in decending order and that the dollare and cents value has been multiplied by 100 to remove the decimal point.



Dim amt, quarter, dime, nickel, penney As Integer

'Right shift the decimal place two positions to get rid of decimals
'we are only interested in whole numbers of coins and by using
'integers we can easily do integer math
'
'I have left off the 5 dollars as you can figure out how do that
'calculation yourself. The 0.92 is converted to an integer by
'multiplying by 100 or in this case just loading 92
'
amt = 92 'This is effectively 0.92 x 100

quarter = amt \ 25 'integer division Note the slash leans left
'regular division the slash leans right

amt = amt Mod 25 'modulo division returns the remainder from integer division

dime = amt \ 10
amt = amt Mod 10 'Mod computes remainder and reassigns it to the amount left

nickel = amt \ 5
amt = amt Mod 5 'at this point the remainder left is in pennies

penney = amt 'just to clearly indicate the amount left in pennies


Now just print your coin values into labels on the form for display
