The Volume of a Circular Slab calculator computes the cubic yards (volume) of concrete a circular slab based on the radius and depth.
INSTRUCTIONS: Choose units and enter the following:
Volume of Concrete (V): The volume is returned in cubic yards. The surface area (A) is returned in square feet, and the perimeter (P) is returned in feet.. However, these can be automatically converted to compatible units (e.g. cubic meters) via the pull-down menu. The calculator also returns the equivalent volume in the number of different size bags (BG) of concrete as follows: 40lb bags, 60lb bags and 80lb bags. Finally, the calculator returns the estimated water (WTR) requirement.
The calculator also returns the surface area and perimeter of the circular slab.
