Density distribution A right circular cylinder with height 8 cm and radius 2 cm is filled with water. A heated filament running along its axis produces a variable density in the water given by ρ ( r ) = 1 – 0.05 e – 0.01 r 2 g/cm 3 ( ρ stands for density here, not the radial spherical coordinate). Find the mass of the water in the cylinder. Neglect the volume of the filament.
