Question

The volume of a cylinder is 81 cubic feet. What is the volume of a cone that fits exactly inside the cylinder?

Answer 1

@Abmon98 Help with this one too? :P kinda the same

Answer 2

sure :)

Answer 3

Okay so what now :p

Answer 4

Now,Do you know the formula?

Answer 5

The volume of a cone is 1/3 * pi * r^2 * H @hba

Answer 6

@Abmon98

Answer 7

is the radius or height given

Answer 8

check your book

Answer 9

Nope only the volume @Abmon98

Answer 10

is the answer 27

Answer 11

I have no idea I don't know how to find it haha and it isn't multiple choice

Answer 12

when both shapes are fitted so they share the same radius and height so 1/3*81

Answer 13

So then the answer WOULD be 27

Answer 14

yes

Answer 15

\[volume~ of~ cylinder~ v=\pi~r ^{2}h\]
\[volume~of~cone~ v1=\frac{ 1 }{ 3 }\pi r ^{2}h\]
\[\frac{ v1 }{ v }=\frac{ \frac{ 1 }{3 }\pi r ^{2} h}{ \pi r ^{2}h }=\frac{ 1 }{ 3 },v1=\frac{ 1 }{3 }v\]
