Since we have that the volume of a sphere is given by:

And we have that the diameter equals 3.6ft, we then will have a volume of:

Since we have that the volume is approximately 13.74 ft^3, then the best approximation in the problem is A. 13.6 ft^3.

Answer:
042
Step-by-step explanation:
The first clue tells you the possibilities are ...
6__, _8_, or __2
The second clue eliminates 6__ and tells you the possibilities are ...
18_, _81, 1_2, 48_, _42
The third clue tells you two of the correct digits are 0 and 2, since 6 has already been eliminated by the first two clues. This only leaves 042.
042 is consistent with the last 2 clues.
The 3-digit key is 042.
I'll have Martin as X and Melvin as Y.
So the equation for X is, 15(starting point) and +5 every set.
Here's a table
________________
The amount of sets|Lbs -------->This one's for Y
__________________ ________________
0 | 15 0 | 60
1 | 20 1 | 50
2 | 25 2 | 40
3 | 30 3 | 30
4 | 35
On the third set, tables help. I'll do the first question in the comments
Ok, what you need is a note to get your notes gather them up so you can write down answers you will need for your test that's all I have that my advice and take your time be careful taking the test ok good luck!
