The volume of a cylinder can be calculated by the product of the area of the base times the height of the shape. It is expressed as follows:
V = πr²h
We calculate as follows:
320π in³= π (r²) (5 in)
64 in² = r²
r = 8 in
Hope this answers the question. Have a nice day.

Answer: All these numbers are the cube of consecutive numbers ,the cube of 1 is 1, the cube of 2 is 8 ,3 is 27 ,4 is 64 and so the next number which is 5 , it's cube will be 125 and so the series will be 1, 8, 27, 64, 125 ,216 and so on…!
2.8*10^12 cells/ 2000= 1.4*10^9 cells.
The number of cells the scientist uses in the second experiment is 1.4*10^9 cells.

Given that a movie producer conducted a survey after a preview screening of her new
movie to find out how the film would be received by viewers from
different age groups.
Given the table that shows the numbers of viewers in
different age groups who rated the film excellent, good, average, and
poor.
Viewer's Age Group Excellent Good Average Poor Marginal Total
16–25 52 42 12 7 113
26–35 33 50 5 9 97
36–45 58 12 28 34 132
46–55 25 17 22 12 76
56+ 12 5 3 8 28
Marginal Total 180 126 70 70 446
<span>The number of viewers from the 46 - 55 age group who rated the film excellent is 25.
Therefore, the percentage of the total survey group who </span><span>rated the film excellent and also was from the 46-55 age group</span> = 25 / 446 x 100% = 5.61%
