Not sure how a radio can help.
If you are given the radius (including units) of a sphere, the volume is 4/3*pi*r3 cubic units. Then mass = density*volume, in the appropriate units.
Multiply them: density*volume = mass
Volume = mass / density
Density = (mass) divided by (volume)Mass = (Density) times (volume)
You can find the mass of an object by multiplying its volume by its density. The formula to calculate mass is: mass = volume x density. Simply plug in the given values for volume and density to calculate the mass of the object.
Density = mass/volumeMass = (density) x (volume)Volume = mass/density
Density = Mass/Volume So you'd need the mass.
v= m/d v is volume m is mass d is density
The formula to find the density is d=m/v
You need also the mass of the material: volume = mass/density. After you measure the mass of the object, then divide by the density, to find volume.
Density is calculated by dividing the mass of an object by its volume. The formula for density is: Density = Mass ÷ Volume. Once you have the mass and volume values, you can plug them into this formula to find the density of the object.
let v-be the volume m-be the mass d-be the density w-be the weight g-gravity we know that, v=m/d and w=mg, where, m=w/g thus, v=(w/g)/d this is now the derived formula to find the volume when density and weigth are given. -by: -kidz-
Well its quite easy: Density=Mass/Volume Volume=Mass/Density SO if mass and density of a cube are given you can easily find its volume.
