The formula is d=C/π.

The diameter is 2 times the radius

The formula for the circumference using the radius is 2πr.

in order to do this backwards, we would have to do 16÷2÷π, but we're not looking for the radius.

Therefore, we take out the ÷2 part, which would be 16÷π

16 is the circumference

16÷π=d

d=C÷π

Answer:

4000 gallons.

Step-by-step explanation:

One day's discharge at the mouth of the river is 2 trillion gallons and it can supply all of country A's households for five months.

Now, if there are 100 million households in country A.

Then, the amount of water an average household uses each month will be given by

$\frac{2 \times 10^{12} }{100 \times 10^{6} \times 5} = 4000$ gallons. (Answer)
