To find the volume of dirt removed from the hole, we can calculate the volume of a cylinder. The hole has a diameter of 5 feet, which means the radius is half of the diameter, so the radius is 5/2 = 2.5 feet. The depth of the hole is 5 feet.
The formula for the volume of a cylinder is V = πr²h, where V is the volume, r is the radius, and h is the height (or depth) of the cylinder.
Plugging in the values, we get V = π(2.5)²(5). Using the approximate value of π as 3.14, the volume would be:
V ≈ 3.14 * (2.5)² * 5
V ≈ 3.14 * 6.25 * 5
V ≈ 98.125 cubic feet
Therefore, the volume of dirt removed from the hole would be approximately 98.125 cubic feet.
