Answer:

Volume = 8143.01 surface area =2261.95

Step-by-step explanation:

V=


\pi {r}^(2) h

plug in variables


\pi {12}^(2) 18 = v

use PEMDAS &solve for v

12 squared=144


v = \pi144 * 18

pi times 144 is approximately 452.39


v = 452.39 * 18

V = 8143.01

A=


2\pi(r) + 2\pi {r}^(2)

plug in variables, simplify, use PEMDAS to solve for A
