The formula entirely depends on the shape of the outline being considered.
A few examples include:
-- Circle . . . Area = (pi) (Radius)2
-- Square . . . Area = (length of one side)2
-- Rectangle . . . Area = (length) x (width)
-- Triangle . . . Area = 1/2 (length of the base) x (height)
Other shapes have different formulas.

If you mean a circle then its square footage formula is: pi*radius2
Treat it as a square and half the result.
One thing that can be calculated using a Square Footage Calculator is the Length and Width of a Rectangle, Circle, Square or Triangle. This comes in handy for calculating room sizes.
length x width = area (sq. foot)
The formula for calculating square footage is a=S2 (a = area and s = side) Example, to calculate the square footage of a room that is 15 feet wide and 12 long, you would multiply 15 x 12, which will give you the square footage.

Take your square footage and divide by 9.
If you mean a circle then its square footage formula is: pi*radius2
Treat it as a square and half the result.
One thing that can be calculated using a Square Footage Calculator is the Length and Width of a Rectangle, Circle, Square or Triangle. This comes in handy for calculating room sizes.
Area in square feet = pi*radius2
length x width = area (sq. foot)
length x width = area
To calculate square footage of a pipe you need to use the area formula of a circle, a=1/2bh. then find the circumference of the entire pipe.
You need to use an integral. And the formula for an integral will vary depending on the shape of your non square area.
That depends on why you need the square footage. For building permits, tax assessments, etc. it is the outside; for floor covering of course the inside...
