we know that
Part 1) 
[surface area of a cone without base]=π*r*l
r=3 in
l=slant height ----> 6 in
[surface area of a cone without base]=π*3*6------> 56.52 in²

[surface area of a cylinder]=π*r²+2*π*r*h------> only one base
r=3 in
h=5 in
[surface area of a cylinder]=π*r²+2*π*r*h
[surface area of a cylinder]=π*3²+2*π*3*5-----> 122.46 in²

[surface area of the composite figure]=56.52+122.46-----> 178.98 in²

the answer Part A) is
 178.98 in²

Part B) 
[surface area of the composite figure]
=12*16+2*12*7+2*16*7+5*12+5*16+13*16----> 932 ft²

the answer Part B) is 
 932 ft²

The first time we met

Is a favorite memory of mine

They say time changes all it pertains to

But your memory is stronger than time

I guess, everything does change

Except what you choose to recall

There's a million good daydreams to dream on

But baby, you are my favorite memory of all

Like the night we made love in the hallway

Slept all night long on the floor

Like the winter we spent on Lake Shasta alone

Closer than ever before

And I remember than London vacation

It was you, made the whole thing a ball

There's a million good times I could dwell on

But baby, you are my favorite memory of all
