*[illustration lateral]

Lateral area = 2 pi r h

Top one 

2*pi*18*18

=2035.75 in^2...............A


Bottom one

Lateral Area = 2 * pi * r*h

=2*pi*36*18

=4071.50 in^2...........................B

Add them up

Area = pi*(r1^2-r2^2)

=pi *54*18
=3053.63 in^2..........................C

Add all the three values . Not too sure if you need to add C
