what you want is the lateral surface area

jim_thompson5910 · Answer

the lateral surface area for a cylinder is

LSA = 2*pi*r*h

in this case, 

r = 6
h = 5

jim_thompson5910 · Answer

so 

LSA = 2*pi*r*h

LSA = 2*pi*6*5

LSA = 60*pi

LSA = 60*3.14

LSA = 188.4

So the lateral surface area is roughly 188.4 square inches
