Answer 1

he volume of the cone is 24 cubic units. Find the value of r in the figure. Leave the answer in simplest form.

Answer 2

V = 1/3 * π * r² * h

Answer 3

We are given the volume of the cone and the height of the cone.

Filling in for those variables, we get the following ....

Answer 4

24 = 1/3 * π * r² * 4

The next task is to solve for r.

Answer 5

all i seen is black diamonds with question marks

Answer 6

im seeing *

Answer 7

When those black diamonds come up, refresh the page. Those diamonds are one of many glitches on this website.

Answer 8

oh i see it now

Answer 9

I ran the equation to be solved through Wolfram Alpha and got r = 2.39 which is 2.4 to the nearest tenth. See what you get.

Answer 10

@desfields901 What did you get?

Answer 11

Did you get this: r = 2.39 or r = 4

Answer 12

what do i do on the link

Answer 13

The link is just to show you that there are websites that can solve equations.
Just for awareness. You may want to use it.
I always double-check whatever the website calculates.

Answer 14

no i mean when i go on do i click on something

Answer 15

Yes, you could do that later.

Let's finish this problem.

Answer 16

Did you get r = 2.4 units.

Answer 17

no i meant you aid what answer did i get i mean what do i do to get an answer

Answer 18

said*

Answer 19

Solve this for r to get answer:

24 = 1/3 * π * r² * 4

Answer 20

Do you see r = 2.4 units among your answer options?

Answer 21

no

Answer 22

What are the answer options?

You can post them and then delete them.

Answer 23

a.square root 3
b.2 square root 3
c.square root 2
d.3 square root 2

Answer 24

Two things:
(1) Are you sure that those answers go with this problem?

(2) Look at the posted problem and see if you typed it in correctly.
Was the volume supposed to be 24 π

Answer 25

yes

Answer 26

24 pi is the volume

Answer 27

The original post stated "he volume of the cone is 24 cubic units." with no mention of pi. That is why the answer we got is wrong.

Answer 28

24* π = 1/3 * π * r² * 4

Answer 29

sorry it wouldnt let me copy and paste the pi i forgot to mention that

Answer 30

In those cases, you write "pi" for the symbol.

Answer 31

The revised answer is: r = 3√2

Answer 32

thanks

Answer 33

Answer 34

that was the last one of volumes and pyramids and cones

Answer 35

Okay, what is next? @desfields901

Answer 36

new post then close it ?

Answer 37

Correct, same as before.
