How do you find the square footage of a flat surface?
Length x width = square footage
What is circumference of a circle with 154 square inches?
Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.
A circle that is 18 feet wide what is the square footage?
Assuming you mean 18 ft in diameter. The formula to find the Area of a circle is: A = Pi x R² where Pi is 3.1416 and R² is the radius multiplied by itself. The Radius is one-half the diameter. Using the formula and substituing the values: A = 3.1416 x (9 x 9) = 3.1416 x 81 = 254.4696 sq ft.
Area of a circle with a diameter of 8?
50.2656 square inches The formula to find the area of a circle is ∏r2. Where ∏ is the mathematical constant and r is the radius of the circle. So 3.14 x 42. = 50.27 square cm or yds, (whatever the diameter was in).
What dose it mean to square a circle?
It means that if you take a circle and find its area, you must now find a square with the same area. We cannot square the circle.
How do you calculate square footage of a pipe?
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.
How to find square footage of a circle outside of the 18ft and inside 20ft?
If the 18 stands for the radius, then the area formula : A= Pi r2 can be used. The question is standed strangely.
Square footage of a column?
This will depend on which column you are looking at. You can use the formula in order to find out the answer.
How do you find the square feet in a dome?
You can find the square footage of any shape, including a dome, by taking a few measurements in relation to its base. The base of any dome is typically a circle, and because of this, the measurement you must take to find the square footage is the radius.

By using the formula: area of circle = pi*radius2
How do you find the square footage of a flat surface?
Length x width = square footage
What is the square footage of a 6 foot flat circle?
To find the Square Footage of a 6 foot circle (flat), we must use the equation for Circle Area:Circle Area = pi × r2Since we know that Diameter = 6 feet we Therefore know that Radius = Diameter/2 = 3 feet = rSo, Since, the constant pi = 3.14159 (approximate), we now have all the numbers to put into our Circle Area equation:Square Footage of a 6 foot flat Circle = 3.14159 x 32= 3.14159 x (3 x 3)= 3.14159 x 9= 28.27431Therefore:The Square Footage of a 6 foot Flat Circle = 28.27431 Square Feet (Feet2)
