Determine the water level inside a tank that has a diameter of 40 feet and contains 180,000 gallons of water?

v = pi r^2 h

180000 = pi * 400 * h
h = 450/pi = 143.24

5.61 and .15 is

To determine the water level inside a tank, we will first calculate the height of the water. The formula to calculate the volume of a cylindrical tank is:

Volume = π * (radius^2) * height

Given that the diameter of the tank is 40 feet, we can calculate the radius:

Radius = diameter / 2 = 40 feet / 2 = 20 feet

We can rearrange the volume formula to solve for the height:

Height = Volume / (π * (radius^2))

Now, let's substitute the known values:

Height = 180,000 gallons / (π * (20 feet)^2)

Before we proceed, we need to convert gallons to cubic feet since both the volume and radius are in cubic feet:

1 gallon ≈ 0.1337 cubic feet

180,000 gallons ≈ 0.1337 * 180,000 cubic feet

Height = (0.1337 * 180,000 cubic feet) / (π * (20 feet)^2)

Next, we calculate the height using a calculator:

Height ≈ 10.74 feet

Therefore, the water level inside the tank is approximately 10.74 feet.
