Cylindrical means shaped like a tin can or a length of pipe — round all the way along, flat at each end.
It is the adjective from cylinder, and it does most of its work in technical description: a cylindrical tank, a cylindrical battery, the cylindrical bales left in a field after harvest. Where you would say tube-shaped in speech, an engineer writes cylindrical. The family around it is worth learning together, since they all behave the same way in a sentence — spherical for a ball, conical for a cone, cubic for a cube.
