Use what for \(\pi\) and do you have the formula for the volume of a cone?

Answer 4

no

Answer 5

If you don't have the formula, how did you arrive at your answer?

Answer 6

Sorry i meant yes

Answer 7

I did not get the same answer. here is the formula that I used:
\[v=\frac{1}{3}\pi r^2h\]

Answer 12

Can i ask one more question

Sure, but I heard a rumor that if you don't close out this question and ask it in a new question, you may be suspended. Don't know if that's true. Just FYI...

Answer 14

An hourglass consists of two sets of congruent composite figures on either end. Each composite figure is made up of a cone and a cylinder.


Each cone of the hourglass has a height of 18 millimeters. The total height of the sand within the top portion of the hourglass is 54 millimeters. The radius of both cylinder and cone is 8 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?


68.3

38.4

268.8

230.4

Answer 15

Draw it out to make it easier to understand.

Answer 16

Is the height of the sand 54 or the volume of the sand 54?

Answer 17

height

Answer 18

i mean volume

Answer 19

It seems to me that you need to divide the volume of the sand by the rate it drips to get your answer.

Answer 20
