Wooden dowel displacement?

[oxsign 1]

What's the best way to figure out the displacement for each one of these? They will be about 15.75" long & 1.5" in diameter. I used them on the last build I did for the blazer, and they held strong, and were easy to use. So I'm thinking of using them again with my next one. Thx for the help.

Length * Pi * ( .5 * diameter)^2

This is kind of basic.

edit: unless I am reading the question wrong. lol.
