The volume of a cylinder's formula can be used to find the area of the base.
The formula - r2 h, where r is the cylinder's radius and h is its height, determines the volume of a cylinder.
The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula r2h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder. Any substance that can fill the cylinder consistently with liquid or another material may be used as the material.
The ratio of the base area to the height can be used to calculate the volume of a cylinder

Answer:
B. The coefficients give the molar ration of the reactants
Explanation:
<u>Answer:</u> The pH of the solution is 1.41
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
Given mass of perchloric acid = 581.1 mg = 0.5811 g (Conversion factor: 1 g = 1000 mg)
Molar mass of perchloric acid = 100.5 g/mol
Volume of solution = 150 mL
Putting values in above equation, we get:
1 mole of perchloric acid produces 1 mole of 
ions and 1 mole of 
ions
To calculate the pH of the solution, we use the equation:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
We are given:
![[H^+]=0.0385M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.0385M)
Putting values in above equation, we get:
Hence, the pH of the solution is 1.41
Answer:
C. METHANE
Explanation:
The blue color of both the ice giants can be contributed to the presence of methane in their upper atmospheres. Methane absorbs most of the red light incident on the planets which makes them appear blue in color.
