Answer 2

The formula for volume of a sphere is \[V = \frac{ 4 }{ 3 }\pi r^{3}\] In this problem you are given the diameter bur volume of a sphere require a radius. d=2r. That means a diameter is twice the length of a a radius. r = d/2. Once you find what r is then plug that into the volume of a sphere and you will get your answer.

Answer 3

@snowsurf gave you the formula for volume of a sphere. I know you said that you don't get it, what do you not get?

Answer 4

how to plug it in

Answer 5

the diameter is r*2, so to get r, you need to do d/2

Answer 6

so 18/2

Answer 7

yes

Answer 8

so r = 9, now put 9 into the formula in place of r

Answer 9

18/2^9

Answer 10

18/2^9???

Answer 11

idk

Answer 12

what is 18/2?

Answer 13

6

Answer 14

how do you get 6?

Answer 15

srry 9

Answer 16

Okay. r =9 like you got.

Answer 17

Now you can plug that into the volume of a sphere I gave you

Answer 18

thx u to both of yall I gave both of yall a medal this is to hard and I hve no clue wht so ever how to plug in the numbers

Answer 19

So \[r =9\] the volume of a sphere is \[V = \frac{ 4 }{ 3 }\pi r ^{3} \] Since you know the radius is 9 you can substitute that into the formula.\[V=\frac{ 4 }{ 3 }\pi 9^{3}\] The rest just simplifying the result.

Answer 20

can send e an online calcutor

Answer 21

3053.63 in^3

Answer 22

That is the correct answer.

Answer 23

they send they want want exact so

Answer 24

To get the exact don't compute pi with it.

Answer 25

yes maybe round o something like tht
