What is the square footage of columns 84 inches tall and 26 inches around?

Assuming you are asking for the surface area of a cylinder of height 84 in and circumference (of end) of 26 in: 12 in = 1 ft circumference = 2 x π x radius → radius = circumference ÷ (2 x π) surface_area = 2 x area_of_ends + curved_area = 2 x π x radius2 + height x circumference = 2 x π x (circumference ÷ (2 x π))2 + height x circumference = circumference2 ÷ (2 x π) + height x circumference = (26 ÷ 12 ft)2 ÷ (2 x π) + (84 ÷ 12 ft) x (26 ÷ 12 ft) ≈ 15.91 sq ft
