Question
A water sample shows 0.03 grams of some trace element for every cubic centimeter of water. Brianna uses a container in the shape of a right cylinder with a radius of 9.6 cm and a height of 11.6 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 Brianna collected? Round your answer to the nearest tenth.

Explanation
## Step 1: Calculate the volume of the cylindrical container### Use the formula for the volume of a cylinder,
, where
is the radius and
is the height. ### Radius
and height
.### \(V = \pi \times (9.6)^2 \times 11.6\).## Step 2: Plug in the values and compute the volume###
## Step 3: Calculate the amount of trace element in the volume of water### Use the proportion given in the problem, 0.03 grams per cubic centimeter.### Multiply the volume by the concentration:###
## Step 4: Round the answer to the nearest tenth###
