Question

{I dont get how to do this, help?}
The cylinders are similar. Find the volume of the smaller cylinder. Round your answer to the nearest hundredth.

Answer 1

I know how to get the volume of a normal shape but this ones weird..

Answer 2

The complete problem.

Answer 3

depends what grade/level math this is.

chances are it's supposed to be treated as a circle

Answer 4

around 12th grade math.

Answer 5

i don't get how to do this since im missing the number to get the volume. And what do i do with the bigger shape?

Answer 6

i'd say treat as circle

V = pi * r^2 * h

Answer 7

V=3.14*2.9*11.6= Like that?

Answer 8

and since we know they are similar, that means that their ratios of height to radius (or any other dimensions) are the same.

\[\frac{ r_1 }{ h_1 } = \frac{ r_2 }{ h_2 }\]

Answer 9

you must square the radius:

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

Answer 10

finding height of the smaller one:

\[\frac{ 5.8 }{ 11.6 } = \frac{ 2.9 }{ h_2 }\]

Answer 11

whats the h2 ?

Answer 12

height of cylinder 2

Answer 13

r is radius
