To find the volume of the column, you need to first find the area of the cross-section. In this case the radius is 1.5 feet. Thus the area is pi1.52. The volume is this area multiplied by 12, so the volume comes out at 12pi1.52 which can be simplified to 27pi. Thus the square footage of the column is 27pi ft2 or approximately 84.823 ft2
