A marble cylinder that has a diameter of 42cm and stands 1.25m tall rests on a flat tile deck. What is the pressure excerted on the deck by the cylinder?

Answer 1

I do not know density of marble, rho.

Weight = rho g * volume
volume = pi r^2 h
so
Weight = rho g (pi r^2 h)
pressure = weight/area where area = pi r^2
so
pressure = rho g h

Answer 2

Density of marble is 2.7 x 10^3 kg/m^3... Idk if that helps?
