The Volume of a Circular Slab calculator computes the cubic yards (volume)  Circular Slab  of concrete a circular slab based on the radius and depth.

INSTRUCTIONS: Choose units and enter the following:

• (r) This is the radius of the slab (half of the diameter)
• (d) This is the depth of the slab.
• Bag Size or STANDARD UNITS

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.  These are the STANDARD UNITS.  For DIY convenience, the calculator also can return the number of bags of concrete as follows:

• 40lb bags
• 60lb bags
• 80lb bags

Once you have your answer in cubic units, click on the SYSTEM button and choose the size of bag (above), and vCalc will tell you how many bags you need for that volume of concrete.
