a copper cylinder 1.50 m long and 40.0 cm in diameter stands on one end.what is the mass of the cylinder?

• physics -

You will need to look up the density of copper. Call it p. It is about 8.94 g/cm^3

The mass is pi*r^2*L*p

L and r should be in cm to get the mass in grams. r = 20.0 cm; L =[ 150 cm.

The mass will not depend upon whether it is standing on an end or the side
