Answer:
80\pi

Explanation:

- the equation for the surface area of a cylinder is
A=2\pi rh+2\pi r^(2)

- the equation for this cylinder will be
A=2\pi (4)(6)+2\pi (4^(2))\\

- so,
2\pi (4)(6) = 150.7964474 and
2\pi (4^(2))\\ = 150.7964474

- then
150.7964474 + 150.7964474= 251.3274123

- finally,
251.3274123/\pi = 80

- so the answer in terms of
\pi is
80\pi

hope this helps :)
