Question

A steel cylinder has a length of 2.16in, a radius of .22in, and mass of 41g. what is the density in g/cm^3?

Answer 1

cylinder volume is

pir^2h

plug in and get pi * 2.16 *(.22)^2

density is mass per volume

convert your units and do 41g / your previous answer

Answer 2

41/(3.1416x(0.22x2.54)^2)x2.16x2.54) g/cc
