A 30 in. diameter concrete column is [L] ft tall.  The column is reinforced with [N], #9 rebar running vertically and #4 circular ties spaced at 12 in.  The first tie is 6 in. above the bottom of the column, the last tie is 6 in. below the top of the column, and each tie 9 ft long.  The vertical rebars start at the bottom of the column and extend 6 ft above the top of the column.  Determine the total weight of reinforcement in the column.  Express your answer in lb. to the nearest lb. (Ex. 2,346.25 lb. –> 2,346) Take #9 rebar to weigh 3.40 lb./ft and #4 circular ties to weigh 0.68 lb./ft
