Density is defined as (mass) divided by (volume).
The question only has meaning if it's referring to a spherical object.
The volume of the sphere is [ 4/3 pi R3 ], where [ R ] is the sphere's radius.
We're given the circumference, and we have to find [ R ].
Circumference = [ pi D ] = [ 2 pi R ].
R = (circumference) / (2 pi)
Volume = [ 4/3 pi R3 ] = [ 4/3 pi (circumference/2 pi)3 ] = [ 4/3 pi (circumference)3 / (8 pi3) ]
= (circumference)3 / (6 pi2)
Density = (6 pi2 Mass) / (circumference)3
An ugly expression, to be sure; but that's what you get when you have a circumference and
what you need is a volume.
The formula for mass if density is not given is mass=volume/power
Density = mass/volume ============================
The formula of density is mass/volume. So mass divided by volume
The formula for density is d= (mass)/(volume)
== Density== Mass/ Volume ==
mass=density multiply by volume
volume = Mass * density
Density = mass / volume You can switch around the formula to look like: Mass = density * volume
Volume = mass / Density Mass = Volume * Density Density = Mass / Volume
density=mass/volume volume=mass/density mass=volume
Density = Mass/Volume.
Density is equal to to (mass)/(volume) .
