Answer:
The volume of cylinder is 18 cubic inches.
Step-by-step explanation:
It is given that cone fits exactly inside the cylinder. It means the radius and height of cone and cylinder are same.
Let the radius of cone and cylinder be r and height of cone and cylinder be h.
The volume of cone is
The volume of cylinder is
It means the volume of cylinder is 3 times of the volume of cone.
The volume of cone is 6 cubic inches. The volume of cylinder is
Therefore the volume of cylinder is 18 cubic inches.

Answer:
61,940
Step-by-step explanation:
For a recursive sequence of reasonable length, it is convenient to use a suitable calculator for figuring the terms of it. Since each term not only depends on previous terms, but also depends on the term number, it works well to use a spreadsheet for doing the calculations. The formula is easily entered and replicated for as many terms as may be required.

The result of executing the given algorithm is shown in the attachment. (We have assumed that g_1 means g[-1], and that g_2 means g[-2]. These are the starting values required to compute g[0] when k=0.
That calculation looks like ...
g[0] = (0 -1)×g[-1] +g[-2} = (-1)(9) +5 = -4
The attachment shows the last term (for k=8) is 61,940.
