surface area = 2 x pi x r x h + 2 x pi x r^2
2 x (3.14) x 1 x 12 = 75.36
2 x (3.14) x 1^2 = 6.28
75.36+6.28 = 81.64
if you cant use a fraction or decimal, does the answer need to be in terms of pi?
that would be 2 x PI x r x h = 2 x pi x 1 x 12 = 24PI
2 x PI x r^1 = 2 x PI x 1 = 2PI
24 PI x 2 PI = 26 PI
