Centre of mass of sphere
WebMay 23, 2024 · r C.O.M = 1 M ∭ Ω ρ r d V Where Ω is our region and M is our total mass. Since this region has constant density and is a quarter-sphere, M is easy to calculate - it is simply 4 π ρ 3. We can now cancel out the ρ in the numerator and denominator to be left with r C.O.M = 3 4 π ∭ Ω r d V. Now let's focus on that nasty looking triple integral.
