Answer: 3054 in^3
Step-by-step explanation: The formula for the volume of a sphere is V = 4/3 pi r^3, where r is radius.
Since the diameter is 18in, the radius would be 1/2 or 9in, and plugged in V is
V = 4/3(3.1415)(9)^3

The y intercept = -4
Also, the slope of the line (if needed) is -2.
The easiest way to determine the score is to use a calculator or spreadsheet and the appropriate probability function.
If you want the top 10%, the score corresponds to the 90th percentile. That score is 316.
If you want the top 15%, the score corresponds to the 85th percentile. That score is 313.
