The area of a circle equals pi (3.1415926...) times the radius squared, or pi(r2). So if the distance from the center of the circle to the edge is 2 feet, you would multiply 2 by 2, and then multiply that result by pi, giving an answer of 12.6 square feet (assuming you rounded pi off to 2 decimal places).
pi x radius x radius equals the area of a circle .

How do you calculate the square footage of a 20' diameter circle?
The area of a circle is computed by the formula A = pi * r2 (r is the radius of the circle)For a 20 foot circle, the radius is 10 feet and the area is 314.16 square feet.
What is the square footage of a 27 foot round area?
If you mean a circle then its square footage formula is: pi*radius2
What is the formula to calculate the square footage of a square?
length x width = area (sq. foot)
How do you estimate square footage?
Square footage is the length of your room times the width. For a circular room, measure the diameter (length across the circle), divide by 2 to get the radius (length across half the circle), multiply by pi and square it. The formula for the area of a circle is πr^2, and Pi (π)= 3.1416
Calculate feet to square feet?
There is a formula that calculates square footage for an area. This formula is: Area = Length x Width. By multiplying these two factors you convert feet into square feet.
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 do you calculate the square footage of a 20' diameter circle?
The area of a circle is computed by the formula A = pi * r2 (r is the radius of the circle)For a 20 foot circle, the radius is 10 feet and the area is 314.16 square feet.
What is the square footage of a 27 foot round area?
If you mean a circle then its square footage formula is: pi*radius2
How do you calculate square footage of semi circle?
Area of a semi circle: (pi*radius2)/2 square feet
What is the formula to find square footage in a circle?
Area in square feet = pi*radius2
How do you calculate the square footage of a half circle?
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
What is the formula for figuring square footage?
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.
What is the formula to calculate the square footage of a square?
length x width = area (sq. foot)
Square footage of a circle?
The area of a circle is calculate as:A = pi x r squared If the radius "r" is in feet, the area will be in square feet.
How do you estimate square footage?
Square footage is the length of your room times the width. For a circular room, measure the diameter (length across the circle), divide by 2 to get the radius (length across half the circle), multiply by pi and square it. The formula for the area of a circle is πr^2, and Pi (π)= 3.1416
Calculate feet to square feet?
There is a formula that calculates square footage for an area. This formula is: Area = Length x Width. By multiplying these two factors you convert feet into square feet.
What all can a person calculate by using a square footage calculator?
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.
