The hole volume refers to the total volume of space within a cylindrical hole. It is calculated by squaring the radius of the hole, multiplying by π (pi), and then multiplying by the depth of the hole. This calculation is important in various fields such as construction, engineering, and geology to determine the volume of material that needs to be excavated or filled.
Let's assume the hole radius is 2 ft and the hole depth is 5 ft.
\[ HV = π * 2^2 * 5 = π * 4 * 5 = 62.83 \text{ ft}^3 \]
The hole volume is 62.83 ft³.
Let's assume the hole radius is 3 ft and the hole depth is 10 ft.
\[ HV = π * 3^2 * 10 = π * 9 * 10 = 282.74 \text{ ft}^3 \]
The hole volume is 282.74 ft³.
