Question

Find the volume of a cylinder with a height of 4 meters and a diameter that is 3 times the measure of the height. Use 3.14 for pi, and round your answer to the nearest hundredth.

Answer 1

Use the formula V=1/3 3.14r^2 H

Answer 2

\[
V =\pi r^2h
\]

Answer 3

\[
2r=3, h=4, \pi \approx 3.14
\]

Answer 4

so what do i do from there solve it ?

Answer 5

H=4 and R=4*3/2
H=4 and R=12/2
H=4 and R=6
\[V=\pi 6 ^{2} 4\]
Therefore, your answer is 452.39 meters.

Answer 6

thank you, i was wondering if i had to do 3*3

Answer 7

cause 2r=3

Answer 8

Where did you get 2r=3 from?

Answer 9

wio up at the top

Answer 10

They probably used a different way to solve it from what I'm used to.

Answer 11

Oh did you use V=1/3 (3.14) r^2 H
