Question

Help me pleaseeeeee!!!!!

Answer 1

530.1 cubic feet

Explanation:

The volume of a cylinder is calculated with the formula
`V=\pi r^(2)`
`h`

You are solving for V, the volume. The diameter of the pool is 15 ft, so the radius is half that, 7.5 ft. That radius will be your
`r`. Your height, which is represented by
`h`, is 3 ft.

Now you must solve the equation.

1. Before you do any multiplication, you must square the radius, because of the order of operations.
`7.5^(2)=56.25`.

2. Now, you can multiply all three numbers together. In case you don't have a pi button, pi is approximately equal to 3.14159.
`\pi *56.25*3` ≈
`530.143`.

3. Your last step is to round that value to the nearest tenth. The tenths place is immediately to the right of the decimal. If the number to the right is 5 or larger, you round the 1 up to a 2. in this case, it is not, so your answer is 530.1 cubic feet.
