The formula for the surface area of a cylinder is:
2πrh + 2πr^2

If we substitute in the measurements that we know, you get:

2[tex] \pi [/tex] (3.5) (14) + 2[tex] \pi [/tex] (3.5)^2

If we simplify this expression, we get:

98[tex] \pi [/tex] + 24.5[tex] \pi [/tex]

If you simplify once more, you get

122.5[tex] \pi [/tex] or ≈ 384.85

Therefore, the surface area is 122.5[tex] \pi [/tex] or about 384.85
