or where is the area, and is the radius. (Pi) = 3.14159 should be close enought for most calculations. A=Pi * r * r where is the area, and is the radius. (Pi) = 3.14159 should be close enought for most calculations.

If you mean a circle then its square footage formula is: pi*radius2

8 square feet

A room's dimensions are not dictated by square footage. For example it might be one foot wide and 4400 feet long, or 220 feet long and 20 feet wide. It could assume any shape: oval, round, square, etc. Square footage is a measurement of area.

First of all, you need to know the radius of the tank. Second, what does outside square footage mean?

Any area is measured in square units - square inches, square centimetres, square miles or whatever. If the shape is regular then there is a formula to help you do so. A circle has an area of pi*r*r where pi = 3.14159 and r is the radius of the circle. If r is expressed in feet then the area will be in square feet - even if the shape is not square.

The shape of a pie is circular. If its diameter is d units, the area is 0.25*pi*d^2 square units.

The square footage of a 25,000 gallon pool depends on the shape of the pool. To determine the square footage multiply the floor width with the floor length. Multiply the length by the height of the walls for each wall. Add all these numbers together to get the square footage.
