Question: Ratio of Area to the circumference $$= πr^2 / 2πr = r/2 =$$ ?

Statement 1:In circle X, the ratio of the circumference to the radius is 2π
This is true for any circle and doesn't provide us the radius hence
NOT SUFFICIENT

Statement 1:In circle X, the ratio of the diameter to the circumference is 1/π

2r/2πr = 1/π
This is true for any circle and doesn't provide us the radius hence
NOT SUFFICIENT

Combining also doesn't give us anything new as the statements have no information
