Answer:
Volume = 8143.01 surface area =2261.95
Explanation:
V=
[tex]\pi {r}^{2} h[/tex]
plug in variables
[tex]\pi {12}^{2} 18 = v[/tex]
use PEMDAS &solve for v
12 squared=144
[tex]v = \pi144 \times 18[/tex]
pi times 144 is approximately 452.39
[tex]v = 452.39 \times 18[/tex]
V = 8143.01
A=
[tex]2\pi(r) + 2\pi {r}^{2} [/tex]
plug in variables, simplify, use PEMDAS to solve for A
