r=2m; h=6m
surface area of ends=2%28pi%29r%5E2
surface area sides=2r%28pi%29%28h%29
Sides+ends=2%28pi%29%28r%29%28r%29%2B2%28pi%29%28r%29%28h%29=%282%28+pi+%29r%29%28r%2Bh%29
%282%28+pi+%29r%29%28r%2Bh%29=2%28pi%29%282m%29%282m%2B6m%29=2%28pi%29%282m%29%288m%29=32%28pi%29m%5E2
ANSWER: The surface area is 32%28pi%29m%5E2.
