What is the formula for density of a sphere?

A sphere with a radius of 10 feet has a density of 8 lb/ft³. Work out, to the nearest pound, the mass of the sphere, knowing that density = mass/volume.

What is the formula to determine density?

d = M/V
density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

How do you find density with mass and diameter?

The density can be found with the formula, density equals mass over volume (d = m/v): The mass is given m = 540 grams, you can plug that into the formula first. H is the height or length, R is the radius or half of the diameter, and π can remain or it can be rounded to 3.14.

How do I find the density of a circle?

The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.

How do you find density if you only have mass?

The formula for density is the mass of an object divided by its volume. In equation form, that’s d = m/v , where d is the density, m is the mass and v is the volume of the object. The standard units are kg/m³.

What are the steps to calculating density?

How do you find the density of a hollow sphere?

Alternatively, δV= surface area of the hollow sphere× its thickness. We know that the density of this hollow sphere is f(r), so the mass of the hollow sphere is 4πr2f(r)δr.

How do you find the mass of a sphere with density?

Once you have the volume, look up the density for the material the sphere is made out of and convert the density so the units are the same in both the density and volume. Finally, multiply the volume by the density to the find the sphere’s mass.

How do you find the radius of a sphere when given the density?

What is the formula for density of a cylinder?

The equation for this is pi*h*r^2, where h is the height or length of the cylinder, and r is its radius. Density is the mass or weight divided by the volume.

What is the density of a cube?

The density of an object or substance can be calculated from this equation: density in kilograms per meter cubed is equal to mass in kilograms, divided by volume in meters cubed (p = m / v). So density could be described as the number of kilograms that 1 meter cubed of substance weighs.

How do you find density without mass?

A simple method based on the moment of forces and Archimedes’ principle is described for finding density without measuring the mass and volume of an object. The method involves balancing two unknown objects of masses M1 and M2 on each side of a pivot on a metre rule and measuring their corresponding moment arms.

How do you find the radius of a sphere formula?

Equation of a Sphere, Plus Center and Radius

The equation of a sphere is similar to that of a circle, but with an extra variable for the extra dimension. (x−h)2+(y−k)2+(z−l)2=r2 In this equation, r=radius. The coordinate (h,k,l) tells us where the center of the sphere is.

How does radius related to density?

Planets with radii up to R = 1.5 Earth radii increase in density with increasing radius. Above 1.5 Earth radii, planet density rapidly decreases with increasing radius, indicating that these planets have a large fraction of volatiles by volume overlying a rocky core.

How do you find the density of two objects?

Density is the mass per unit volume. It can be measured in several ways. The most accurate way to calculate the density of any solid, liquid or gas is to divide its mass in kilograms by its volume (length × width × height) in cubic metres. The unit for density is kg/m 3.

How can you measure the density of a non uniform object?

  1. weigh it on a scale for the object.
  2. Submerge it in water, measure the displacement (volume)
  3. Weight/volume = density.

Can density be determined from a single measurement?

Can density be determined from a single measurement? Density is not something that is directly measured. Typically if you want to know the density of something you will weigh it and then measure its volume.

How do you find the density of a regular object?

Method 1: A regular shaped object
  1. Use a ruler to measure the length (l), width (w) and height (h) of the object.
  2. Place the object on the top pan balance and measure its mass.
  3. Calculate the volume of the cube using ( l × w × h ).
  4. Use the measurements to calculate the density of the object.

How do you find density in an experiment?

To find the total Volume displaced, subtract Initial Volume and Volume of Object. To calculate Density divide the Mass in grams by the Volume displaced in milliliters. Finally record whether the object floats or sinks.

What is the density of h2o?

997 kg/m³
Water / Density

What is the density for copper?

8.96 g/cm³ (Near room temperature)
Copper / Density (Near room temperature)

How do you find the density of a marble?

What is the density of 1000 g of water?

1000 kg/m3
