CIRCULAR COLUMN CONCRETE VOLUMNE Formula :  π x radius ²  (sq. ft.) x height of column(ft)  = ft ³/ yd ³ of concrete 27 (cubic ft/yd) Where π = 3.14 and radius = diameter (ft.) of column /2 NB. Inches are expressed as fraction or decimal equivalents. Step 1 : determine the radius of the column. E.g. 4 ’ /2 = 2 ’ Step 2 : calculate the volume using the formula π x radius ²  (sq. ft.) x height (ft)  =  3.14 x (2) ²  x 30  27 (cubic ft/yd)   27 =  376.8ft ³   = 13.96 rounded up to 14 cubic yards 27 NB. For cubic yard, divide by 27.  E.g. depth = 3  ½  (0.292 ’ ), form = 2 ’  x 4 ’ Concrete required = 2 ’  x 4 ’  x 0.292 ’  = 23.36 ft ³  or 23.36/27 = 0.865yd ³

Inches are expressed as fraction or decimal equivalents. Step 1 : determine the radius of the column. E.g. 4 ’ /2 = 2 ’ Step 2 : calculate the volume using the formula π x radius ² (sq. ft.) x height (ft) = 3.14 x (2) ² x 30 27 (cubic ft/yd) 27 = 376.8ft ³ = 13.96 rounded up to 14 cubic yards 27 NB. For cubic yard, divide by 27. E.g. depth = 3 ½ (0.292 ’ ), form = 2 ’ x 4 ’ Concrete required = 2 ’ x 4 ’ x 0.292 ’ = 23.36 ft ³ or 23.36/27 = 0.865yd ³
