WebNov 7, 2015 · 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. The radius of the circle is the distance from the ... WebArea of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2, (Pi r-squared) where r is the radius of the circle. The unit of area is the square unit, such as m2, cm2, etc. Area of Circle = πr2 or πd2/4, square units. where π = 22/7 or 3.14.
