What is the volume of the sphere if a sphere was dropped into water in a graduated cylinder as shown?

40 +25=65

This may look complicated because the volume of the sphere is shown as more than ten and less than twenty ml but using width also. In fact the question is simple because the volume of water the sphere displaces pushes up the level of water in the tube, and it can be easily seen to be 25 ml higher than the original level, before the sphere was dropped into it.
