Measure the volume. Divide by pi (=3.14...) and multiply by 6. Then take cube root.
Or find the surface area, divide by pi, and take square root.
Or balance a large plank on top, make sure it is horizontal, and measure from the floor to the plank.
Or ask on Yahoo!Answers.
Take your pick!

because of the fact it says 18 inch sphere, my first reaction could be that it incredibly is that is diameter. If it have been circumference, it could be an prolonged decimal seeing as C = (pi)(d). desire this facilitates :)
