Question

A cone-shaped container has a height of 240 in. and a radius of 150 in. The cone is filled with a liquid chemical. The chemical evaporates at a rate of 12,000 in3 per week.

How many weeks will it take for all of the chemical to evaporate?
Use 3.14 to approximate pi.


weeks

Answer 1

So first we find the Volume of the Cone then multiply it by 12,000?

Answer 5

i got tagged

Answer 6

Yeah, lets first find the cones volume

Answer 7

Had to switch to phone version. Sorry if replies are slower now

Answer 8

its k bro

Answer 9

Volume of the Cone is 5,652,000

Answer 10

Yeah

Now it's saying that it loses 12,300 a week. So what would we do to find total weeks

For a smaller example

The volume is 50 and it loses 10 a week. That would be 5 weeks. How did we find it? Doing 50/10

Answer 11

so we do 5,652,000 / 12, 300 ?

Answer 12

Correct (It'll be in the 400s)

Answer 13

459.5121

Answer 14

So I'll just round it or? :/

Answer 15

Yeppers

Answer 16

so 460 right?

Answer 17

it doesn't say, so probably either or will do. I say to keep it as it is

Answer 18

460 would be right tho

Answer 19

so do 459?

Answer 20

Yeah 459.5121

Answer 21

it only lets me put 3 digits

Answer 22

459.512 should do

Answer 23

Or 460

Answer 24

That's the problem though

Answer 25

It doesn't really take 460 weeks, it takes 459. So idk if they want you to truncate or not

Answer 26

hmmmm
this is hard lol

Answer 27

If they wanna be completely correct, then I say 459

Answer 28

471 probably? :/

Answer 29

Why 471 if I may ask

Answer 30

Sorry also, but I gotta jet out. I should be on tomorrow. It was nice working with you today. I'd go with 459 personally

Answer 31

Okay. Thanks!
See ya! :)
