Hello!
The equation to find the volume of a sphere you use the equation

r is radius which is half the diameter
put in 3.14 for pi and 12 for r

This gives us the answer of 7234.56 cubic units
Hope this helps!
17.5x12=210
210 divided by 14=15
15x2.50=37.5
37.5
17.5 is feet so you need to divide by 12 for inches which gets 210 and you need each necklace to be 14 inches so you need to divide 210 by 14 which is 15 each necklace costs 2.50 so you multiply 2.50x15
You get 37.5
