**Bosnian**, Saturday, March 31, 2012 at 12:58amC = Circumference

A = Area

r = Radius

C = 2 r pi Divide both sides with 2 pi

C / 2 pi = r

r = C / 2 pi

A = r ^ 2 pi

A = ( C / 2 pi ) ^ 2 * pi

A = ( C ^ 2 / 4 pi ^ 2 ) * pi

A = C ^ 2 / 4 pi

A = 25 ^ 2 / 4 pi

A = 625 / ( 4 * 3. 14 )

A = 625 / 12.56

A = 49.761 m ^ 2

A = approx. 50 m ^ 2
