Answer 1

The length of 4 trillion dollar would be $4\times 10^9$

Step-by-step explanation:

Since we have given that

Annual expenditure = 4 trillion dollars

1 dollar bill = 0.0001 m

So, the thickness would be

$4\times 10^{12}\times 0.001\\\\=4\times 10^{12}\times 10^{-3}\\\\=4\times 10^{12-3}\\\\=4\times 10^9$

Hence, the length of 4 trillion dollar would be $4\times 10^9$
