hii!!
here's ur answer...
given the diameter is 21cm
therefore radius is 21/2cm
height of the cylindrical container is 27cm
if the label is placed by leaving margin of 2cm from the top and base then the height of the label will be=27-(2+2)
=27-4
=23cm
we know that CSA of cylinder=2πrh
=2×22/7×21/2×23
=2×11×3×23
=1518cm²
hence the area of the label is 1518cm².
hope this helps..!
