Explanation:
To find the cost to rent one water tank, we need to calculate its volume and then multiply it by the rental cost per cubic foot.
The formula for the volume of a cylinder is given by:
V = πr²h
where V is the volume, π is a mathematical constant approximately equal to 3.14, r is the radius of the cylinder, and h is the height of the cylinder.
In this case, the radius (r) is 3 feet, and the height (h) is 2 feet. Plugging these values into the formula, we get:
V = 3.14 * (3^2) * 2
V = 3.14 * 9 * 2
V = 56.52 cubic feet
Now, we can multiply the volume by the rental cost per cubic foot:
Cost = V * $4
Cost = 56.52 * $4
Cost = $226.08
Therefore, the cost to rent one water tank is $226.08.
