Your ground storage tank is 15 feet high and 30 feet in diameter. About how much water can it hold?

To determine the volume of water a cylindrical ground storage tank can hold, you can use the formula for the volume of a cylinder:

[ V = \pi r^2 h ]

where ( V ) is the volume, ( r ) is the radius of the cylinder, and ( h ) is the height.

In this case, the tank has a diameter of 30 feet, which means the radius is half that size—15 feet. The height of the tank is given as 15 feet.

Plugging in the numbers:

1. Calculate the radius squared: [ r^2 = 15^2 = 225 , \text{square feet} ]

2. Use the height: [ h = 15 , \text{feet} ]

3. Now, substitute these values into the volume formula: [ V = \pi (225)(15) ]

4. Simplifying further, you get: [ V = 3375\pi , \text{cubic feet} ]

5. Using the approximate value of ( \pi ) (3.14), the volume in cubic feet is: \
