Volume of anything = (its mass) divided by (its density)
regardless of what shape it happens to be.
how do you find the mass of a sphere Volume x density => 4/3(pi)(r)3 x density
you have to divide the mass by the volume then measure the ends then you found your answer
calculate the volume using the formula: Vsphere = (4/3)*pi*r^3 then calculate density by Density = Mass/Volume
Density = mass/ volume volume= 4/3(pie)(r^3) ***r= radius in meters** so find volume then divide mass by volume and there you go.
Density is the mass per unit volume. e.g. kg/m3. But you've only given one of the quantities needed - we still need the volume of the sphere.
Density = mass / volume. You have the density of aluminum and the mass of the aluminum sphere. The volume of a sphere is 4/3*Pi*r^3. Therefore volume = 4/3*Pi*r^3 = mass / density. Solve for r, which is the radius of the sphere.
You need to know if the sphere is solid or hollow. You also need the "density" in terms of pounds weight per unit volume. Then Volume = Mass/Density And Radius = cuberoot[3*Vol/(4*pi)]
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.
The volume of a sphere is 4 / 3 * pi * r3
Volume of a sphere = 4/3*pi*radius3
use the formula 4/3*π*radius3 to find the volume of a sphere.
Calculate the volume of a full sphere, then divide that by 2.
