Solution

To find the height of the cylindrical water tower, we can use the formula for the volume of a cylinder, which is V = πr²h, where V is the volume, r is the radius, and h is the height.

Step 1: Find the radius. The diameter of the water tower is given as 20 ft, so the radius would be half of that, which is 10 ft.

Step 2: Substitute the known values into the formula. We know the volume V is 7,540 ft³ and the radius r is 10 ft. So, the formula becomes 7,540 = π(10)²h.

Step 3: Simplify the equation. (10)² is 100, so the equation becomes 7,540 = 100πh.

Step 4: Solve for h. To isolate h, divide both sides of the equation by 100π. So, h = 7,540 / (100π).

Step 5: Calculate the value. When you do the division, you get approximately 24 ft.

So, the approximate height of the water tower is 24 ft.
