MHB Integration Application: Find the force on each end of the cylinder

[andvaka]

A cylinder shaped container of tar has a diameter of 2m. If it is half full of tar with a density of 920 kg/(m^3) and is on it's side, find the force on each end.

Helpful hints:
920 kg per m^3 is the mass density not the weight density. Take g= 9.8 m/ sec^2Please assist. I'm not sure at all how to approach this or what relationships to use.​

I would be interested in seeing your solution. Normally the problems involving cylinders and the density of a material within that cylinder involve calculating the work done by pumping out a certain amount.
