Answer:

Step-by-step explanation:

Firstly, we know that the number of $10 bill is 1/10 of $1 and 1/5 times that of $5 bills.

We also know that the amount of $10 bills equal that of $1 bills and the total amount of bills we have is $225.

Now, let the amount of $10 be x. This means the amount of $1 bill is 10x and the amount of $5 bill is 5x.

Mathematically:

$10[x] + $1[10x] + $5[5x] = $225

$10x + $10x + $25x = $225

$45x = $225

x = $225/$45 = 5

This means she have only 5 $10 bills

$S=2\pi r h+2\pi r^2\\
2\pi rh=S-2\pi r^2\\
h=\dfrac{S-2\pi r^2}{2\pi r}\\
h=\dfrac{S}{2\pi r}-1$
