Question

Does anybody know this? I don't have much time and Also it is not the forth option. What is the approximate surface area of the cylinder shown?

Answer 1

Answer:

C) $628\:\text{cm}^2$

Step-by-step explanation:

$SA=2\pi rh+2\pi r^2\\\\SA=2\pi(\frac{10}{2})(15)+2\pi(\frac{10}{2})^2\\ \\SA=150\pi+50\pi\\\\SA=200\pi\:\text{cm}^2\approx628\:\text{cm}^2$
