Question

Each cone of the hourglass has a height of 15 millimeters. The total height of the sand within the top portion of the hourglass is 45 millimeters. The radius of both cylinder and cone is 6 millimeters. Sand drips from the top of the hourglass to the bottom at a rate of 10π cubic millimeters per second. How many seconds will it take until all of the sand has dripped to the bottom of the hourglass?

Answer 1

126
108
18
29

Answer 2

where do i even start?

Answer 3

How did you get from an extremely basic geometry question to an advanced calculus question in a matter of minutes?

Answer 4

Honestly my class is confusing

Answer 5

I already work for a company where I answer questions on this level and I get paid to write the answers. I'd rather go to that site and answer these kinds of questions than do it for free here. Sorry to disappoint you. I can answer up to basic level calculus, but for something like this, and only because of the amount of time required to answer, I can only devote so much time here.

Answer 6

what is the site?

Answer 7

Slader.com, but I'm already assigned books to work on. I can't work on the book you're working on unless the question is in one of my already assigned books.

Answer 8

huh so what do i need to do

Answer 9

never mind the site is blocked on this computer

Answer 10

thank you anyway

Answer 11

That's not surprising

Answer 12

You'd have access to all the answers in your textbook.

Answer 13

i just needed to be explained to but thanks bro i might need help with another simple one soon though

Answer 14

Calculate the volume of sand, the cone will be completely filled and the cylinder will have sand up to the 30 mm level.
Volume of sand will = the volume of the cone: 1/3 * pi * (6 mm)^2 * 15 =
1/3 * pi * 36 * 15 =180 pi cubic mm the cylinder will have a volume of sand equal to:
pi * (6 mm)^2 * 30 mm=pi * 36 sq mm * 30 mm=1080 pi cubic mm.
The total sand is the sum: 1080 pi cubic mm +180 pi cubic mm = 1260 pi cubic mm.

Answer 15

Yeah I get you, but what you don't understand is that I was supposed to start working six hours ago. I procrastinated thus far and now I really have to start working.

Answer 16

the sand travels at a rate of 10 pi/sec so the sane will take (1260 pi)/10 pi/sec=
=126 pi seconds. ... i may have made an error so .... someone should look at this @Hero

Answer 17

well i think it makes sense and it looks right but i am not sure either

Answer 18

Looks right @Cupcake123456 . I was having trouble imagining what the hourglass would look like. But I realize that the bottom portion would be the cone and the cylinder would be above the cone and all the sand would fill both. I think you have the right idea, but double-check your calculations.

Answer 19

@Cupcake123456 - You should always post where you get your sources from.
>Brainly.

Answer 20

@umm no i didnt use brainly but thank you anyway only sources i used were my brain and a calculator

Answer 21

Also, @Cupcake123456 remember this is not an answer-giving site. This is an "explain to the user how to do the problem then let them do the work themselves" site.

Answer 22

you told me dat in my inbox yeen have to come back and post it ...
