Answer:
2100
Step-by-step explanation:
Volume of sphere = 4/3πr³
r is radius.
Radius = diameter/2 = 16/2 = 8
Volume = 4/3(3.14)(8)³
Volume = 2143.57
Rounded to nearest tenth would be 2144.7 in³
The answer is D.

Let "a" and "b" represent the numbers of people on teams Alpha and Beta, respectively. The problem statement tells you
a = (1/4)b
b - 6 - 12 = a + 12
The first equation can be rewritten to give an expresion for b:
b = 4a
This can be substituted into the second equation to get
4a -18 = a +12
3a = 30
a = 10
There were originally 10 people on team Alpha.
