Considering the volume of the cylinder, it is found that Cai has collected 327.9 grams of trace element.
<h3>What is the volume of a cylinder?</h3>
The volume of a cylinder of radius r and height h is given by:
.
In this problem, we have that the radius and the height are given, respectively, by:
r = 9.3 cm, h = 17 cm.
Hence the volume of the cylinder in cubic centimeters is given by:
![V = \pi \times (9.3)^2 \times 17 = 4619](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20%5Ctimes%20%289.3%29%5E2%20%5Ctimes%2017%20%3D%204619)
A water sample shows 0.071 grams of some trace element for every cubic centimeter of water, hence the amount of trace element is given by:
0.071 x 4619 = 327.9 grams.
