The assessment of metallic alloy microstructure is not conducted by the application of volume fractions. Volume fractions, though applied to mixtures, are not appropriate in evaluating metallic crystal structures, even though there may be significant size differentials between the atoms of the metals in the alloy. Metallic crystal structures are evaluated by other methods (x-rays, electron microscopy, etc.) Got links if you want them.

You are supposed to multiply the length by the edge that is a fraction and divide it by 2 and multiply by 3. Then you add 3.14. You should get your answer
To find the half of a fraction, multiply the given fraction by 1/2 or 0.5.
Remember that in math, "of" usually means "times". To find a fraction of a fraction, multiply them.
You turn the decimal into a fraction. Then you can find the equivalent fraction.
To simplify a fraction, find the GCF of the numerator and denominator and divide them by it. If the GCF is 1, the fraction is in its simplest form.
To find the volume of the alloy, use the formula for density: Density = Mass / Volume. First, calculate the volume of water displaced by the alloy when immersed: Volume of water displaced = Mass in air - Mass in water. Then, use the density of water (1g/cm^3) to find the volume, as the volume of water displaced equals the volume of the alloy. Finally, calculate the density of the alloy by dividing its mass by the volume obtained.
The formula for calculating the density of an alloy is: Density = (Mass of alloy) / (Volume of alloy). To find the mass of the alloy, you would typically weigh it using a balance. To find the volume of the alloy, you can measure its dimensions (length, width, and height) and calculate the volume using the formula for the volume of a rectangular prism: Volume = Length x Width x Height.
If you are given its makeup you should be able to make up a list of its constituent metals or elements and the weight fraction of each. Then find the densities of each. Multiply the fraction of each times its density to get the 'weight' of that element in a unit weight the alloy. Add up these 'weights' to get the weight of a unit of the alloy.
measure each side then multiply the fraction of the denominator

Usually with a pure element, you only have atoms of that element, example element C. So whatever the phase may be (eg. solid or liquid), the composition will only consist of the C atoms. An alloy on the other hand has more than one composition. For this example, lets say that the alloy consists of element A and B. Both the pure elements and the alloy have different phases they can be in, but the alloy's phases will consist of A + B. If the metals were to be heated up and cooled down, looking at a phase diagram you would see the different phases the alloy and the pure metals are in at that particular temperature. Looking at a phase diagram steel as an example, alloy of Iron and Carbon, with say a .05 wt % carbon, you can heat it up past 910 degrees C to austenitize the alloy reaching the Austenite phase. Then following straight down the phase diagram you will see the different phases the steel achieves. With TTT curve, however, time is another variable to consider. The steel can be austenitized and rapidly quenched to a certain temperature and held at that temperature yielding a certain microstructure due to the phase it is held at. Long story short, TTT curve most likely applies to alloys, particularly steel, whose time dependence shape the microstructure. Most likely you won't find a TTT curve for a pure element because the microstructure will not be too affected by heat treatment.

To calculate the volume of an arc, you first need to determine the volume of the entire shape that the arc is a part of, such as a cylinder or a sphere. Then, you calculate the total volume of the shape using the appropriate formula (e.g., V = πr^2h for a cylinder). Next, you find the central angle of the arc and use it to determine the fraction of the total volume that the arc occupies. Finally, you multiply the total volume by this fraction to find the volume of the arc.
The slope can be a fraction.
To find the mole fraction of solute, you need to know the moles of solute and solvent. In this case, the moles of solute can be calculated by multiplying the molarity of the solution by the volume of the solution. Once you have the moles of solute and solvent, you can find the mole fraction of solute by dividing the moles of solute by the total moles of solute and solvent.
To find the half of a fraction, multiply the given fraction by 1/2 or 0.5.
It depends on what you want to find the volume of!
