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.

A water reservoir has the shape of a right circular cone with its circular base of radius R = 160 m at ground
level (z = 0 m). Rain fills the reservoir over the winter; when full, the reservoir depth is h =
summer, water from the reservoir is pumped up to ground level for drinking, irrigation, etc. At the end of the
summer, the volume of water left in the reservoir is only 3/7 of its full capacity.

(a) Find the depth of the water in the reservoir at the end of the summer.
Answer: Depth = 52.776
m
(b) Find the total work done to lift water out of the reservoir during the summer.
Answer: W = 54461207640
J.
(Recall the density of fresh water: p =
1000 kg/m.)
