256 Pi. The area of a circle is equal to the radius square multiply by pi
The area of a circle = Pi*r2 where r is the radius and Pi is approximately equal to 3.14.
Using 3.14 as Pi the area of circle is: 12.56
The area of a circle is the radius square times pi. pi is equal to around 3.14159 Area = (3.14159)(302) = 2827.431mm
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
