Question

WILL GIVE FAN AND MEDAL!!!!!!!!!!!!!!!!

A hose dispenses 1413 cm3 of water every minute into a cone with a radius of 60 cm and a height of 150 cm.

How long will it take to fill the cone?
Use 3.14 to approximate pi.

______ min

PLS HELP!!!!!!!!!!!!!

Answer 1

Find the volume of the cone. Divide the flow rate by the cone volume and you will get the time needed to fill the cone (in minutes).

Answer 2

How to I find the flow rate? @shawmoes

Answer 3

You are given the flow rate as 1413 cm^3 / min

Answer 4

Would the cone volume be 180000?

Answer 5

What is the equation for the volume of a cone ? It's \[V= \pi*r^2*h/3\]

Answer 6

So would the answer be 565487, or 127?

Answer 7

Or would it be 400? I have to round it.

Answer 8

I get the volume as 565714 cm^3 , but if you use 3.14 to approximate the volume , you would get 565200 cm ^3.

Answer 9

So use 565200 cm ^3 because the question asks for you to use 3.14 as pi.

Answer 10

So would it be 400?

Answer 11

For the minutes, 400 Minutes?

Answer 12

Correct :)
