Mass of a sphere of diameter 1cm whose density is 900 kg/m^3, Physics

mass=volume * density.By using this formula we can find the mass of sphere.

Volume of sphere=(4/3)pi*r^3

V=(4/3)*3.14*(1*10^-2)^3=4.187*10^-6

Mass=(4.187*10^-6)*900=3768*10^-6kg

density = mass/ volume

given denstiy = 900kg/m3 and diameter = 1cm so radius(R) = 0.5 cm = 0.005m

900 = mass/ (4/3 π R3 )

Mass = (900*3 π R3 )/4 = (900*3* π *(0.005)3 )/ 4 = 2.650718801×10?4 Kg

radius=0.5cm

Volume=4/3pi x (0.5)3

          =0.52 cm3

          = 0.52 x 10-6 m3

 

Mass= Density x Volume

        = 900 x 0.52x10-6  kg

        =0.468 g
