How do you find the area of a circle in square feet?
The formula for determining the total square feet in a circular area is: A = Pi x R2 (Area = Pi x R-squared). This formula may mean nothing to you so here’s a explanation: To determine the total square footage in a circular area you will first need to determine the radius (R) of the circle.
What is the area of my circle?
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
What’s the area of a 12 inch circle?

How to calculate the square footage of a circle?
The diameter should be measured in feet (ft) for square footage calculations and if needed, converted to inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m). The formula: Area of a Circle = π x (Diameter/2)^2. π = 3.142.
How do you calculate the diameter of a circle?
The formula used to calculate the circle diameter is: ø = 2 x √(A / π) Symbols. ø = Circle diameter; A = Circle area; π = Pi = 3.14159… Area of Circle. Enter the area contained within a circle. Diameter of Circle. This is the diameter of a circle that corresponds to the specified area.
Is the circumference of a circle an irrational number?
All of these values are linked with the mathematical constant π, or pi, which is the proportion of a circle’s circumference to its diameter, and is nearly 3.14159. Pi or π is an irrational number, means that it cannot be stated accurately as a fraction (though it is often estimated as 22/7).
How to calculate the perimeter and area of a circle?
