Answer: 2/12 --> 1/6
3/2 --> 1 1/2
Step-by-step explanation:
2/12 can be simplified by dividing the top by 2 and the bottom by two. 2 is the GCF (greatest common factor) of both 2 and 12.
3/2 is a improper fraction so you have to make it a proper fraction. To do that you get 1 and 1/2. <-- this is for simplest form.

Find the volumes of the two cones and subtract.
V = 1/3 * pi * r^2 * h
V = 1/3 * 3.14 * 6^2 * 9
Simplify exponent:
V = 1/3 * 3.14 * 36 * 9
Multiply:
V = 339.12
V = 1/3 * pi * r^2 * h
V = 1/3 * 3.14 * 3^2 * 6
Simplify exponent:
V = 1/3 * 3.14 * 9 * 6
Multiply:
V = 56.52
Subtract the two volumes:
339.12 - 56.52 = 282.6
So the Garden Landscaping Company purchased 282.6 ft^3 of gravel.
