Given

R->"The outer radius of the cylinder"=6mRThe outer radius of the cylinder=6m

r->"The inner radius of the cylinder"=2mrThe inner radius of the cylinder=2m

h->"The height of the cylinder"=8mhThe height of the cylinder=8m

The material volume of the cylinder

V="outer volume "- " inner volume"V=outer volume inner volume

=>V=piR^2h-pir^2hV=πR2hπr2h

=>V=pih(R^2-r^2)V=πh(R2r2)

=>V=3.14xx8xx(6^2-2^2)m^3=803.84m^3V=3.14×8×(6222)m3=803.84m3
