Brass sphere

Find the weight of a brass ball with an outer radius of 12 cm, a wall thickness of 20 mm if the density of the brass is 8.5 g/cm3.

Correct result:

m =  25.9202 kg

Solution:

R=12 cm h=20 mm cm=20/10  cm=2 cm r=Rh=122=10 cm  ρ=8.5 g/cm3  V1=43 π R3=43 3.1416 1237238.2295 cm3 V2=43 π r3=43 3.1416 1034188.7902 cm3  V=V1V2=7238.22954188.79023049.4393 cm3  m1=ρ V=8.5 3049.439325920.2338 g  m=m1 kg=m1/1000  kg=25920.2337872/1000  kg=25.92 kg=25.9202 kg
