Answer: 30.2
Explanation:
The mean is calculated by taking the sum of the values and dividing by the count.
For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:
186
6
=
31
And we can do the same for the men:
116
4
=
29
And now we can combine the sum and count of the men and women to find the mean for the office:
186
+
116
10
=
302
10
=
30.2

Answer:
V =972 pi mm ^3
Step-by-step explanation:
The diameter is 18 so the radius is 1/2 of the diameter
18/2 = 9
r=9
The volume of a cylinder is
V = pi r^2 h
V = pi (9)^2 12
V =972 pi mm ^3
