## How to determine the volume, area and perimeter of a circular (round) slab concrete foundation?

### The volume of concrete of a circular (round) slab concrete foundation according to the formula:

**V = Π * d ^{2} * h **

* V* is the volume of concrete;

* Π* = 3.14159 is a mathematical constant (the number “Pi”);

* d* is the diameter of the slab;

* h* is the thickness (height) of the slab.

### The area of a circular (round) slab concrete foundation according to the formula:

**S = Π * d ^{2} / 4**

* S* is the area of the slab;

* Π* = 3.14159

* d* is the diameter of the slab;

### The lateral surface area of a circular (round) slab concrete foundation according to the formula:

**A = Π * d * h**

* A* is the lateral surface area of the slab;

* Π* = 3.14159

* d* is the diameter of the slab;

* h* is the thickness (height) of the slab.

### The perimeter of a circular (round) slab concrete foundation according to the formula:

**P = Π * d**

* P* is the perimeter of the slab;

* Π* = 3.14159

* d* is the slab diameter.
