The area of a circle is given by the formula A =π r2 = 300000
Therefore r2 = 300000/π = 95492.97 : r = √95492.97 = 309.02
The Circumference of a circle is given by the formula C = 2πr
C/A = 2πr/π r2 = 2/r therefore C = 2A/r = 600000/309.02 = 1941.62 ft
If the area of a circle is 300000 ft2 then the circumference is 1942.62 ft
