Spherical ball of lead has a diameter of 5.5 cm . what is the mass of the sphere if lead has a density of 11.34 g/cm3? (the volu
umka21 [38]
To know the mass of the sphere given the density , we first define density as

D = Mass / volume

now we have a value of density but doesn't have volume so we compute for it using the given radius 5.5 cm

V = <span>(4/3)πr^3 

so 
mass  =  D (volume)
mass = 11.34 (</span>(4/3)π(5.5)^3 )

mass = 7902.96 g
