Help with simple Physics homework.?

This is pretty simple Physics homework, it has a lot of to with Chem, but I want to see what others get to see if I got the right answers.

1. If the density of mercury is 13.6 g/ml, what is the mass in grams of 3426 ml of the liquid?

2. A copper cylinder, 12 cm in radius, is 44 cm long,. If the density of copper is 8.9 g/cm^3, calculate the mass in grams of the cylinder. (assume pi=3.14)

1) Density is mass divided by volume, so mass equals volume times density. If every ml of liquid contains 13.6 g of mass, then how many grams would 3426 ml contain?

2) Find the volume of the cylinder using V = pi*radius^2*length and then solve like number 1.
