Question

What is the radius of a cone if its height is 9 inches and its volume is 150.72 cubic inches? (Use 3.14 for π.)

Answer 1

Simply divide 150.72 by 9 to find the radius, witch would be 16.74666666666667, to double check just invers the problem.

Answer 2

nope wrong

Answer 3

Really then cause if you inverse and do 16.74666666666667 x 9 you would still get 150.72 mate.

Answer 4

yes but do you know whats a volume of a cone??

Answer 5

Yes, the the total area or size of the shape.

Answer 6

whats the formula

Answer 7

Mate, I know math I take collage math classes and I'm only in the 10th grade.

Answer 8

haha me too brother

Answer 9

what's the formula?

Answer 10

i guess you don't know it??

Answer 11

The formula would be !50.72 (your volume) divided by 9 (the hieght) to get 16.74666666666667 (the diameter) then divide by 3.14 to get the radius 5.333333333333334.

Answer 12

Sorry I had to type it and dpo all the math again.

Answer 13

ok the for mula is \[V=\pi r^2h\]

Answer 14

Yes that is pretty much what I did exept I filled in the numbers to be more exact

Answer 15

Yes that is pretty much what I did exept I filled in the numbers to be more exact

Answer 16

so you're technically not done yet

Answer 17

No, the formula is done the radius is 5.333333333333334

Answer 18

you forgot to square root it

Answer 19

Ahh, man this is liek middle school stuff so... its easy to forget!

Answer 20

*Like

Answer 21

So am I right??

Answer 22
