The square footage of a radius is meaningless, but if you mean the square footage of a circle of radius say R, the answer is 3.142 x R x R
First of all, you need to know the radius of the tank. Second, what does outside square footage mean?
If it's a circle, around 1017.88 square feet.
Area = pi*40002 = 50265482.46 square feet

Area of a circle: pi*radius squared
Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2
Surface area for a circle is pi * radius squared If the diameter is 25 feet, then the radius is 12.5 feet, and the square footage is pi * 12.5 * 12.5 Or about 491 square feet
First of all, you need to know the radius of the tank. Second, what does outside square footage mean?
If it's a circle, around 1017.88 square feet.
A=3.14x5x5=78.5 sq. ft.
Area of the circle in square feet = pi times radius squared
Area = pi*40002 = 50265482.46 square feet
To find the square footage of a circle, you first need to calculate the area of the circle using the formula A = πr^2, where r is the radius of the circle. In this case, the radius is half of the diameter, so the radius is 2 feet. Substituting the radius into the formula, we get A = π(2)^2 = 4π square feet. Therefore, the square footage of a 4-foot circle is approximately 12.57 square feet.
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
That quantity is usually called "area".The area of any circle is (pi) (radius)2 .Area = (pi) (11 inches)2 = 380.133 square inches (rounded)To convert square inchage to square footage, divide by 144.380.133 square inches = 2.64 square feet (rounded)
