Nice question, Bunuel!
Target question: What is x?
Statement 1: The radius is one-half the length of the diameter.
This property is true for EVERY circle in the universe, which means x (the radius) can have any value.
Statement 1 is NOT SUFFICIENT
Statement 2: The ratio of the circumference to the diameter is π.
This property is true for EVERY circle in the universe, which means x (the radius) can have any value.
Statement 2 is NOT SUFFICIENT
Statements 1 and 2 combined
Since both statements are true of any circle in the universe, x can have any value.
The combined statements are NOT SUFFICIENT
