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

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

Explanation:

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