The Weight of a Semicircle Concrete Slabcalculator computes the weight or mass of a semicircular shaped concrete slab based on the radius (r), the depth (D) and mean density of concrete.
INSTRUCTIONS: Choose units and enter the following:
Semi-circle Mass (M): The calculator returns the weight in pounds. However, this can be automatically converted to compatible units (e.g. kilograms, tons, metric tons) via the pull-down menu.
M = ½•π•r²•D
