The **Circular Slab Calculator** computes the amount of materials needed for a circular slab.

The Circular Slab Calculator has the following functions:

- Circular Slab - Volume, Surface Area and Forms: This computes the amount of concrete, the surface size and the length of the forms needed for a rectangular slab.
- Circular Slab - Weight: This computes the weight of the concrete in a rectangular slab
- Rebar and Concrete in a Circular Slab: This computes the length and weight of rebar in a rectangular slab. It also computes the total weight of the slab including concrete, taking into account the concrete displaced by rebar.
- Cost of Concrete Using Bags: This computes the cost of pouring a volume of concrete based on the unit price of a bag of concrete. The user has three options for bag size (80 lb, 60 lb and 40lb)
- Cost of Bulk Concrete: This compute the cost of pouring a volume of concrete by the cubic yard. It also allows for delivery cost based on mileage and pumping costs.
