Question

A water sample shows 0.063 grams of some trace element for every cubic centimeter of water. Savannah uses a container in the shape of a right cylinder with a radius of 6 cm and a height of 17.6 cm to collect a second sample, filling the container all the way. Assuming the sample contains the same proportion of the trace element, approximately how much trace element has Savannah collected? Round your answer to the nearest tenth.

Answer 1

The volume of a cylinder with radius r and height h is given by:

`V=\pi\cdot h\cdot r^2`

For r = 6 cm and h = 17.6 cm, we have:

`V=\pi\cdot17.6\cdot6^2`

V=1990.5 cm³

Therefore, a total of 1990.5*0.063 = 125.4 grams of the trace elemente was collected by Savannah
