Answer:
V = 56.816 cm³
Explanation:
Given that,
The measured value of the cylinder is 54.5 cm³
The percent error in the measurement of the volume is 4.25%
We need to find the actual volume of the cylinder.
Firstly, we can find the error in the calculation as follows :
It is mentioned in the problem that, the teacher told her that she was 4.25% too high in her determination of the volume. It would mean that,
Total volume = 54.5 + 2.316 = 56.816 cm³
Hence, the actual volume of the cylinder is 56.816 cm³.
Answer:
The answer is
<h2>2.71 g/cm³</h2>Explanation:
The density of a substance can be found by using the formula
From the question
volume of marble = 1564 cm³
1 kg = 1000 g
4.24 kg = 4240 g
mass = 4240 g
The density is
We have the final answer as
<h3>2.71 g/cm³</h3>Hope this helps you
Answer:
The mass of silver is
Explanation:
Given that,
The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.
The density of silver is 10.49 g/mL.
We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,
1 gram = 10⁻⁶ Megagram
Hence, the mass of silver is
