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:
- (r) Radius of the slab (half of the diameter)
- (d) Depth of the slab.
Volume of Concrete (V): The volume (V) is returned in cubic yards. However, this can be automatically converted to other volume units (e.g. cubic meters) via the pull-down menu. The calculator also returns same volume in the number of different size bags of concrete as follows:
- 40lb bags
- 60lb bags
- 80lb bags
The calculator also returns the surface area and perimeter of the circular slab.
