The answer to the first question is 8 segments.
The reason is being is that a diameter consists of two points.
If you have 16 points on the circumference of a circle then you can have at most 8 diameters formed since two points are needed for each diameter. Since you have 17 points, the extra point doesn't form a diameter since it doesn't have another point to use.
2. You can't solve x/z because the two variables are independent. The answer is N/A because there is no relationship connecting y to w or x to w.
3. The length * width of sandbox = 300 * 200 = 60,000 square centimeters of sand. To determine height occupied by the sand:
600,000 / 60,000 = 10 centimeters. 10 cm is the height of the sand.
