(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Radius Problem

A brass rod (density = 8470 kg/m3) is 12cm long and weighs 20N. What is the radius of the rod?

I'm confused when finding area. I don't think I'm using the right variables.

volume = mass/density

v = 2.04 kg / 8470 kg/m3 = 2.4X10^-4

Area = volume/length?

A = 2.4X10^-4 / .12m = .002m

A = pi r^2

r = .03m
