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.

Question

anonymous · Answer

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

anonymous · Answer

$$
V  =\pi  r^2h
$$

anonymous · Answer

$$
2r=3, h=4, \pi \approx 3.14
$$

anonymous · Answer

so what do i do from there solve it ?

dangerousjesse · Answer

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.

anonymous · Answer

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

anonymous · Answer

cause  2r=3

dangerousjesse · Answer

Where did you get 2r=3 from?

anonymous · Answer

wio up at the top

dangerousjesse · Answer

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

anonymous · Answer

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