Remember the Circle Area(A) eq'n
A = pi r^(2)
Hence
A = 3.141592.... x (3^(2))
A = 3.141592... X 9
A = 28.27433388... units^(2)
A ~ 28.27 unit^(2) to 2.d.p..

Formula of a radius when the area is given?
Since you said radius, I assume you mean Circle or Sphere. Circle: Area = Pi * radius^2 therefore, Radius = Square Root of (Area/Pi). Sphere: Area = 4/3 Pi * Radius^3 therefore, Radius = CubeRoot of (3/4 * Area/Pi)
