Note....There are  ≈ 39.37 inches to one meter

 

So we have

 

4000   =  2 * pi^2 * (.59 * 39.37) * r^2

 

( 4000 / [ 2 * pi^2 * (.59 * 39.37) ] )  = r^2    take the square root of both sides

 

2.95  in ≈  r

 

And there are ≈ 2.54 cm to  one in

 

So....radius  ≈  2.54 * 2.95   ≈  7.493 cm
