[tex]What is the value of x? leave your answer in simplest radical form.[/tex]for this case we have by definition, that the surface area of a cylinder is given by:

[tex]sa = 2 \pi * r * h + 2 \pi * r ^ 2[/tex]

where:

r: it is the radius of the cylinder

h: it's the height

according to the data we have:

[tex]r = 7\\h = 2[/tex]

substituting:

[tex]sa = 2 \pi * 7 * 2 + 2 \pi * 7 ^ 2\\sa = 28 \pi + 98 \pi\\sa = 126 \pi[/tex]
