Question

Maria want to make a footstool in the shape of a cylinder, as show below. She wants to fill the footstool with foam and cover it with fabric. r=12in by h=18in

Answer 1

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
