Question

A water sample shows 0.056 grams of some trace element for every cubic centimeter

of water. Liam uses a container in the shape of a right cylinder with a diameter of 14
em and a height of 13.6 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 Liam collected? Round your answer to
the nearest tenth.

Answer 1

The first time you were able and you had to do something about

Answer 2

Liam has collected approximately 155.2 grams of the trace element.

Step-by-step explanation:

Calculate the volume of the cylinder:

Radius = Diameter / 2 = 14 cm / 2 = 7 cm

Volume = πr²h = π * 7² cm² * 13.6 cm ≈ 972.7 cm³

Multiply the volume by the trace element concentration:

Trace element = 0.056 grams/cm³

Total trace element = 972.7 cm³ * 0.056 grams/cm³ ≈ 54.8 grams

Round to the nearest tenth:

Total trace element ≈ 54.8 grams ≈ 155.2 grams

Therefore, Liam has collected approximately 155.2 grams of the trace element in his water sample.
