ANSWER

[tex]320.28 {cm}^{2} [/tex]

EXPLANATION

The surface area of a cylinder is given by

[tex]SA = 2\pi \: r(r + h)[/tex]

From the diagram, r=3cm and h =14cm.

We substitute the known values into the formula to get:

[tex]SA = 2\pi \: 3(3+ 14)[/tex]

[tex]SA = 2(3.14)\: 3(3+ 14) [/tex]

[tex]SA =320.28 {cm}^{2} [/tex]

The second choice is correct.
