Question

The volume of the cylinder is 1,311.9. Find the height of the cylinder to the nearest tenth of an inch. How do i do this?

Answer 1

Well the volume of a cylinder is

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

If we know Volume to be 1311.9

\[\large 1331.9 = \pi r^2h\]

Now this as it is is impossible to do since we do not have the radius length...

Does the question have that listed?

Answer 2

Ah 12...

So we have \[\large 1331.9 = 12^2 \pi h\]
\[\large 1331.9 = 144 \pi h\]
\[\large h = \frac{1331.9}{144 \pi}\]

Answer 3

so the height would be 9.1in?

Answer 4

Not quite what I get...

Answer 5

wait i think i did it wrong that time, is it 2.9?
