Answer:
Population 120 given the survey, sample 90 who answered the survey.
Step-by-step explanation:
The entire amount of employees who even received the surveys at all was 120. Because the total number was 120, 120 is the population.
Only 90 out of 120 surveys were received, so 90 is the sample because it is part of 120.
Hope this helps :)
V =

r^2h/3
V = 3.14 x 4^2 x 6/3 (remember r is 1/2 of the diameter)
V = 3.14 x 16 x 2
V = 100.5
