How would u measure square footage of a round house.
Square footage is a unit of measurement for area. The formula to find the area of a circle is A = pi * r^2. Measure, in feet, from the outer wall to the center of the house. This is your radius. Now multiply this number by itself, and then multiply that total by 3.14. This is the square footage. As of 2009, the average house size in the US is 2,422 square feet, compared to 1,700 sq ft in the 1980s.
