Question

volume of a cylinder with a ratio of 4/2 or 2/1
the volume of the smaller cylinder is 70
my answer either 560 or maybe 280 sing another formula im leaning more towards 560 ...

Answer 1

using*

Answer 2

4:2 is the ratio.so obviously the 2 is the smaller volume so your proportion will become...

4:2 = x: 70 right? so...

\(\Huge \frac{4}{2} = \frac{x}{70}\)

what do you do now?

Answer 3

the ratio 4:2 is the ratio of the volume of the larger cylinder to the volume of the smaller cylinder right?

Answer 4

well /2 can be 2/1
then should be 2 x 2 x2 =8/1
8x70=560

Answer 5

4/2

Answer 6

wait..where'd you get 2 x 2 x 2 again?

Answer 7

its either 8/1 or 4/1

Answer 8

from 4/2 it can be 2/1 right then you have o multiply its a rule
the 2 x 2 x2 =8/1

Answer 9

however im unsure if its times 3 or times 2 sense its 4/2

Answer 10

8/1 is NOT equal to 4/1 what they meant was that 4/2 can be simplified to 2/1

Answer 11

yeah but then you multiply the top number of the alrdy simplified number

Answer 12

you cannot multiply them...you're not being asked to multiply..they just simplified it for you

Answer 13

ok

Answer 14

so that's how you'll get your x...

\(\Huge \frac{4}{2} = \frac{x}{70}\)

or

\(\Huge \frac{2}{1} = \frac{x}{70}\)

just cross multiply
